Take a look around your home.

0:00:040:00:06

Can you be sure that every appliance is safe?

0:00:070:00:11

Is everything a company tells you about a product true?

0:00:130:00:16

And are you getting the best value for your money?

0:00:180:00:21

With the help of the country's top experts,

0:00:220:00:24

we're going to see what it takes

0:00:240:00:26

to test the household products we use every day.

0:00:260:00:29

We'll discover how they're pushed to their limits.

0:00:320:00:34

We'll put the makers' claims on trial.

0:00:370:00:40

And show you how to make your money go further.

0:00:410:00:45

You'll find these products in any ordinary house.

0:00:450:00:49

But this is no ordinary house, and no ordinary street.

0:00:490:00:53

This is the Watchdog Test House.

0:00:530:00:56

Hello. We're deep inside one of Britain's leading science centres.

0:01:010:01:06

Here at the Building Research Establishment,

0:01:060:01:09

some of the products and materials that we use every day

0:01:090:01:13

are put to the test to make sure that they're safe,

0:01:130:01:16

environmentally friendly, and that they don't fall apart.

0:01:160:01:20

Coming up on today's programme,

0:01:200:01:22

thinking of buying a tyre second hand? Check carefully.

0:01:220:01:26

A 19-and-a-half-year-old second-hand tyre.

0:01:260:01:29

Michael's life was worth far more than this.

0:01:290:01:32

We take to the track to find out

0:01:320:01:33

just how dangerous a defective tyre can be.

0:01:330:01:36

Two fitness instructors. Three days. No showers.

0:01:370:01:41

Do you really need a deodorant that claims to last 72 hours?

0:01:410:01:44

-This is going to get smelly.

-You bet!

0:01:440:01:47

Plus sharp edges, choking hazards

0:01:470:01:50

and an astonishing array of harmful chemicals.

0:01:500:01:53

We reveal why safety laws on children's toys

0:01:530:01:55

have become so stringent.

0:01:550:01:57

We drive more than 7,000 miles on average every year,

0:02:010:02:05

so you want to be sure your tyres are safe.

0:02:050:02:08

But if you buy yours second-hand, beware.

0:02:080:02:11

What seems like a good deal could turn out to be a bad risk.

0:02:110:02:15

It is completely outrageous that a tyre that was nearly 20 years old

0:02:170:02:23

was on a vehicle transporting 53 kids

0:02:230:02:27

on a 500-mile round trip

0:02:270:02:28

on a motorway doing over 60 mph.

0:02:280:02:31

In September 2012, Michael Malloy was on his way home

0:02:310:02:35

from a music festival on the Isle of Wight

0:02:350:02:37

when the coach he was travelling in crashed.

0:02:370:02:40

When she heard, his mother Frances rushed to the hospital.

0:02:400:02:44

I said, "Just take me to Michael," you know, "Just..."

0:02:440:02:47

And...

0:02:470:02:49

the police liaison officer just said, "There's no easy way to say this.

0:02:490:02:53

"He died at the scene. He died instantly."

0:02:530:02:56

Michael was among three people who died on the coach that day.

0:02:580:03:02

The cause of the accident was clear -

0:03:020:03:04

a blow-out on the front near side tyre of the coach

0:03:040:03:08

had caused it to veer left off the dual carriageway,

0:03:080:03:12

mount the embankment, crash through a fence and into a tree.

0:03:120:03:16

The tyre had been bought second-hand

0:03:160:03:19

and was almost 20 years old.

0:03:190:03:21

It was older than Michael. It was older than the coach itself,

0:03:210:03:24

and it was actually legal.

0:03:240:03:26

The company was fined more than £4,000 for

0:03:260:03:29

allowing the use of a vehicle with a tyre with ply or cord exposed,

0:03:290:03:34

and for allowing too many people on the coach.

0:03:340:03:37

But there's currently no legislation

0:03:370:03:40

governing how old a second-hand tyre can be,

0:03:400:03:43

something Frances is campaigning to change.

0:03:430:03:46

A 19-and-a-half-year-old second-hand tyre,

0:03:460:03:49

it's completely and utterly outrageous,

0:03:490:03:52

and I just won't give up or give in on this.

0:03:520:03:55

Michael's life was worth far more than this.

0:03:550:03:59

Whilst there's no legislation

0:04:000:04:02

governing how old a second-hand or part-worn tyre can be,

0:04:020:04:06

there are rules on the condition in which they are allowed to be sold.

0:04:060:04:10

And it's the job of Trading Standards Officers to enforce them.

0:04:100:04:14

Today we're following officers in Sandwell, in the West Midlands

0:04:140:04:18

as they carry out routine spot checks

0:04:180:04:20

on a number of premises on their patch.

0:04:200:04:22

First up, this garage on an industrial estate.

0:04:240:04:27

The owner explains he imports his part-worn tyres from abroad

0:04:270:04:31

and that he does check them.

0:04:310:04:33

But despite his reassurances,

0:04:330:04:34

the officers inspect the tyres that are on sale for themselves.

0:04:340:04:39

They look at their condition. That includes tread depth,

0:04:390:04:42

whether there are any defects,

0:04:420:04:44

and also whether they are labelled correctly.

0:04:440:04:47

-You've got a part worn stamp?

-Yes.

0:04:470:04:49

The inspection starts well, but things soon go downhill.

0:04:500:04:53

You see the kink in the bead there?

0:04:530:04:57

Yep.

0:04:580:04:59

You see on this one?

0:04:590:05:00

-Obviously, that's the bead wire exposed.

-Bloody dangerous.

0:05:000:05:04

This one, it's had a nail penetration.

0:05:050:05:09

When a tyre's been penetrated,

0:05:090:05:10

the cavity formed by the penetration has to be plugged or filled.

0:05:100:05:15

In total, Brian and his team find seven tyres on sale

0:05:150:05:18

at this first garage that could pose a risk to unsuspecting drivers.

0:05:180:05:23

We checked roughly about 30 tyres and we found that 25% of them failed

0:05:230:05:29

due to damage in the tyre wall and different issues with the beading.

0:05:290:05:33

But there's worse to come.

0:05:330:05:35

That is an absolute potential killer,

0:05:350:05:38

and the side wall has collapsed.

0:05:380:05:40

Find out later just how many tyres fail Trading Standards testing.

0:05:410:05:45

We'll also be taking to the track

0:05:450:05:47

to demonstrate how dangerous driving with a part-worn tyre can be.

0:05:470:05:51

Now, we've all been there.

0:05:560:05:58

You're getting ready for the perfect night out.

0:05:580:06:00

Little black dress to hand.

0:06:000:06:02

Just one final swipe of anti-perspirant deodorant

0:06:020:06:05

before heading out. And then, disaster strikes -

0:06:050:06:08

white marks all down your clothes.

0:06:080:06:10

And that's despite some of them claiming to be invisible.

0:06:100:06:14

Yes, Sophie, we're talking sprays, roll-ons, sticks -

0:06:160:06:20

an explosion of anti-perspirant products

0:06:200:06:23

all claiming to leave no white marks. What's their secret?

0:06:230:06:26

Dr Laura thinks it might all be down to the size of the particles.

0:06:280:06:31

If you make large particles

0:06:310:06:33

which rub off onto clothing,

0:06:330:06:35

you'll see them much more clearly than if you make smaller particles,

0:06:350:06:40

so even if they do rub off, you won't see them with the naked eye.

0:06:400:06:43

For the purpose of our tests, we've chosen three stick deodorants

0:06:450:06:48

as we could only find three on the market brave enough

0:06:480:06:51

to claim the powers of invisibility.

0:06:510:06:53

They are Dove Invisible Dry Anti-white Marks,

0:06:530:06:56

Nivea Invisible Black & White White Mark Protection for black clothes,

0:06:560:07:01

and Sure Crystal Clear Invisible.

0:07:010:07:03

We'll also compare those products

0:07:030:07:05

to one that makes no claims about invisibility whatsoever.

0:07:050:07:09

Time to get technical.

0:07:090:07:11

Dr Laura wipes an equal amount of each deodorant

0:07:110:07:14

onto a chemical substance which mimics the behaviour of the skin.

0:07:140:07:17

Clever. She then places them under the microscope.

0:07:170:07:21

First up - Dove Invisible Dry.

0:07:210:07:24

You can see those streaks there, so we have got some particles,

0:07:240:07:28

but they're certainly not so small that you can't see them,

0:07:280:07:30

so you wouldn't expect, if you were to look at it in real life,

0:07:300:07:34

to appear invisible,

0:07:340:07:35

you would expect to see particles of this size.

0:07:350:07:37

It's a similar story with Sure Invisible.

0:07:370:07:40

Now, again, you can see large particles under here

0:07:400:07:43

so you would not expect this to be invisible.

0:07:430:07:46

As for the Nivea product...

0:07:460:07:48

Looks quite good, actually.

0:07:480:07:49

As you can see, it has a very different texture about it.

0:07:490:07:52

It looks quite flat, looks quite even

0:07:520:07:54

and nowhere near the particles as large or clumped together.

0:07:540:07:58

So it seems that under the microscope

0:07:580:08:00

the Nivea deodorant looks like it has the smallest particles

0:08:000:08:03

and therefore might be more invisible than the others.

0:08:030:08:06

As for the one that makes no invisibility claims...

0:08:060:08:09

I think it clearly shows

0:08:090:08:10

the particles are clumping together more.

0:08:100:08:13

You get larger particles, and therefore you would be less likely

0:08:130:08:16

to expect this one to be invisible.

0:08:160:08:19

Interesting. So that's the particle size in the lab.

0:08:190:08:22

How will that translate to where it really matters?

0:08:220:08:26

That's right, armpits!

0:08:260:08:28

We've got three volunteers, who work in this gym in Huddersfield.

0:08:280:08:31

three black T-shirts, and our three stick deodorants

0:08:310:08:34

boasting that they won't leave any white marks.

0:08:340:08:38

They'll apply each of those to their left armpit.

0:08:380:08:40

And on the right, they'll use the stick deodorant

0:08:400:08:43

that makes no claims about invisibility.

0:08:430:08:46

Got that? Good.

0:08:460:08:47

A few minutes to let the deodorants dry. Talk amongst yourselves.

0:08:470:08:51

OK, on go the black T-shirts.

0:08:510:08:53

And now take them off again.

0:08:530:08:55

Time to assess the damage.

0:08:560:08:58

That's my invisible.

0:08:590:09:01

But there's some white marks there, aren't there?

0:09:020:09:05

First up - Dove.

0:09:050:09:07

Both this product and the one that makes no claims

0:09:070:09:09

did leave some white marks.

0:09:090:09:11

Not much in it, is there?

0:09:110:09:13

Next, the Sure so-called Invisible.

0:09:140:09:17

That's made more of a mess

0:09:170:09:18

on the T-shirt than the product that makes no claims!

0:09:180:09:22

There's quite a lot, isn't there?

0:09:220:09:24

But what about the Nivea Invisible product?

0:09:240:09:26

The one that had the smallest particles in the lab?

0:09:260:09:29

No white marks on that side of the T-shirt.

0:09:290:09:31

But on the other side, the no-claims product has left a small mark.

0:09:310:09:35

So the winner of this test is not just Nivea - it's also science,

0:09:350:09:39

as that's just what the lab particle size test predicted.

0:09:390:09:42

Our tests, of course, are just a snapshot.

0:09:440:09:46

Unilever, who makes Dove and Sure,

0:09:460:09:48

say they have confidence in their products,

0:09:480:09:50

which are proven to have effective anti-white marks protection

0:09:500:09:53

under rigorous consumer and scientific testing.

0:09:530:09:56

But some companies also make bold claims about how long

0:09:580:10:01

anti-perspirants will last.

0:10:010:10:02

Wonder why these fitness instructors look nervous? We've just told them

0:10:020:10:06

they're going to be testing 72-hour anti-perspirants

0:10:060:10:09

and won't be allowed to wash for three days.

0:10:090:10:12

Find out what happens later on.

0:10:120:10:13

Recognise her? This is a Cindy doll from 1963.

0:10:190:10:24

She had the washable bobbed hair,

0:10:240:10:26

the stripy T-shirt and even arms and legs that moved freely.

0:10:260:10:30

But she also needed something extra,

0:10:300:10:32

around 16 pages of safety documentation.

0:10:320:10:36

Now, these aren't on sale anymore

0:10:360:10:38

but if you compare her to this, a modern-day Barbie,

0:10:380:10:42

under current legislation,

0:10:420:10:44

she requires thousands of pages of official paperwork.

0:10:440:10:48

So what was it that sent the toy industry into legislation overdrive?

0:10:480:10:52

Whatever it was, I'm sure Lynn Faulds-Wood will know all about it.

0:10:520:10:56

MUSIC: 1980s Watchdog theme

0:10:560:10:58

Welcome to Watchdog. On tonight's programme...

0:10:590:11:01

All these people have written to us...

0:11:010:11:04

'Watchdog's uncovered a stockingful of dangerous toys over the years.'

0:11:070:11:12

My baby would love this, he's nutty about aeroplanes,

0:11:120:11:14

but wait till you see what's in the wing - a razor blade!

0:11:140:11:17

How many of you have actually bought toys like these in the past

0:11:170:11:20

for Christmas or birthdays

0:11:200:11:21

and they turn out to have hidden spikes in them, or perhaps

0:11:210:11:25

nasty chokeable chunks of stuffing coming out...

0:11:250:11:29

'But even in the 1980s,

0:11:290:11:31

'toys were actually among the most regulated products you could buy.'

0:11:310:11:35

And nowadays it's even more so - they test for sharp edges,

0:11:350:11:39

harmful chemicals, small parts that children could swallow.

0:11:390:11:43

But that certainly hasn't always been the case.

0:11:430:11:47

In fact, you only need to look at some of the toys of the 1950s

0:11:480:11:52

here at the Museum of Childhood

0:11:520:11:54

to see why we've had to develop such strict rules.

0:11:540:11:57

Here's a little tool set, and inside you've got a saw

0:11:570:12:01

and tools that are all original

0:12:010:12:03

and working for making craft items.

0:12:030:12:06

And then here you've got an amazing little soldering kit.

0:12:060:12:09

You could be up in your bedroom soldering away.

0:12:090:12:11

The first British Safety Standard for toys was introduced in 1961.

0:12:110:12:16

It touches on everything we use today, pretty much,

0:12:180:12:21

but in a very short way, and appropriate to the toys of the time.

0:12:210:12:24

They had metal toys then,

0:12:240:12:26

so it specifically mentions metal edges

0:12:260:12:28

and that they shouldn't be sharp.

0:12:280:12:30

But at 15 pages, compared to today's standards, they lacked detail.

0:12:300:12:35

Now, when you think about edges in general, they shouldn't be sharp,

0:12:350:12:39

but it says what is sharp and what isn't sharp and how to test that.

0:12:390:12:43

So that paragraph has become ten pages to actually explain that.

0:12:430:12:47

Another worry has always been

0:12:470:12:49

whether a toy contains any parts that pose a choking hazard.

0:12:490:12:54

This is Billie and his Barrels,

0:12:540:12:56

a very popular development toy produced in the 1940s.

0:12:560:13:00

As you can see, each cup comes apart

0:13:000:13:02

as you go down in size, all the way to little Billie right here.

0:13:020:13:06

But obviously, little Billie is so tiny,

0:13:060:13:08

he'd be a complete choking hazard today,

0:13:080:13:10

so you wouldn't be allowed to have something so small.

0:13:100:13:13

But this version dates from the 1980s.

0:13:130:13:14

You can see Billie's much bigger here

0:13:140:13:16

and he's also fixed into his barrel

0:13:160:13:18

to make him safer for children to play with.

0:13:180:13:21

And these days you can test whether a toy could be a choking hazard

0:13:210:13:25

by using what's called a small parts cylinder.

0:13:250:13:29

Everything for under-threes cannot have small parts.

0:13:290:13:32

So this cylinder, it looks odd but it's shaped

0:13:320:13:35

specifically for the mouth,

0:13:350:13:37

and a small part, like that £2 coin

0:13:370:13:41

would fit in entirely.

0:13:410:13:42

So you can have that in toys but there would be a warning

0:13:420:13:45

on the packaging saying, "Not for under-threes due to small parts."

0:13:450:13:48

Here are some of those he considered to be potentially dangerous.

0:13:480:13:51

But as we exposed in the 1980s,

0:13:510:13:54

it's not just toys that could present a risk.

0:13:540:13:58

Take, for instance, these harmless looking things here - pen tops.

0:13:580:14:01

During the last series, we told you

0:14:010:14:03

how at least ten children have died after putting pen tops

0:14:030:14:06

in their mouths, inhaling them and blocking their windpipes.

0:14:060:14:09

'So by 1987, thanks to our pressure,

0:14:090:14:12

'manufacturers had changed their designs.

0:14:120:14:15

'The most common solution?'

0:14:150:14:17

They put a hole in the lid,

0:14:170:14:19

so that if a child does inhale that and get it stuck in their windpipe,

0:14:190:14:23

they can breathe until you get them to hospital.

0:14:230:14:26

And this has become the standard not just in this country,

0:14:260:14:29

but right across the world.

0:14:290:14:31

But there are less obvious dangers, like those posed by chemicals.

0:14:330:14:38

Many old toys were covered in lead paint.

0:14:380:14:41

Others contained potassium nitrate and even mercury.

0:14:410:14:45

This chemistry set dates from about the 1930s.

0:14:450:14:49

It would have been the ultimate present for a boy

0:14:490:14:52

for a birthday gift or Christmas gift

0:14:520:14:54

and it's full of an amazing array of chemicals.

0:14:540:14:56

Then you'll see these very simple games, maze games. They use mercury.

0:14:560:15:01

There's something really nice about the property of mercury,

0:15:010:15:04

how it runs round, but today,

0:15:040:15:05

you wouldn't find mercury in a toy like this.

0:15:050:15:08

Although the likes of poisonous lead paint

0:15:080:15:10

and mercury were long gone by the 1990s,

0:15:100:15:14

it was another chemical found in plastic toys

0:15:140:15:17

that was causing concern.

0:15:170:15:19

The chemical DIMP is a member of a family of compounds

0:15:190:15:22

called phthalates.

0:15:220:15:24

It's added to PVC, to turn hard brittle vinyl like this

0:15:240:15:29

into soft, squeezy vinyl like this.

0:15:290:15:32

That makes the PVC capable of being moulded into toys.

0:15:320:15:36

It wasn't until 2005 that controls on the use of this compound

0:15:370:15:40

were written into European Standards.

0:15:400:15:43

And it's chemicals in toys that remain the biggest worry today.

0:15:430:15:47

It's increased from the '60s

0:15:470:15:49

where I think there were six or seven chemicals,

0:15:490:15:51

to now we have thousands of chemicals

0:15:510:15:53

that are restricted within toys.

0:15:530:15:55

In fact by 2011 - the last time the standards were updated -

0:15:550:15:59

it's fair to say they'd become pretty comprehensive.

0:15:590:16:02

We did an exercise where we took a toy -

0:16:020:16:04

it's quite a complicated toy, it's electronic and it moves.

0:16:040:16:07

That had 2,500 separate pages of legislation that applied to it.

0:16:070:16:12

So quite a significant change in 40 to 50 years

0:16:120:16:16

to where we are today.

0:16:160:16:18

Since 1989, we've been able to check

0:16:180:16:21

whether a toy that we buy meets or even exceeds

0:16:210:16:24

strict European standards by looking for this symbol.

0:16:240:16:28

The Lion mark.

0:16:280:16:29

But although there've been huge advances in design and regulations,

0:16:290:16:33

manufacturers can't always guarantee

0:16:330:16:36

that every single toy on the market will be safe.

0:16:360:16:40

Maybe a mould has produced a sharp edge where it shouldn't

0:16:400:16:44

because it's aged and worn. Maybe they've bought a batch of materials

0:16:440:16:47

that doesn't conform with the latest restrictions on chemicals.

0:16:470:16:51

When that happens, they will assess what toys have been affected,

0:16:510:16:56

how many of those toys there are, where they went in the market -

0:16:560:16:59

they need to know all that.

0:16:590:17:01

And they'll contact those retailers and they'll put up notices

0:17:010:17:03

and they'll try to get them back from customers.

0:17:030:17:05

And then they'll go back to the standards

0:17:050:17:08

to actually rectify the issue.

0:17:080:17:09

These days, the big risk to our children's playtime

0:17:090:17:13

comes from illegal toys that don't meet European standards.

0:17:130:17:17

Let's hope Trading Standards officers find them

0:17:170:17:20

before our children do.

0:17:200:17:22

Next, solar panels.

0:17:270:17:28

They've long been available as a way to use the sun

0:17:280:17:31

to generate electricity and hot water for your home.

0:17:310:17:34

They help the environment and they can also help your finances as well.

0:17:340:17:38

But which panels should you choose,

0:17:380:17:40

and how long before they start to pay off?

0:17:400:17:43

Well, here at the Building Research Establishment, they test them.

0:17:430:17:47

So who better to ask than Peter White.

0:17:470:17:49

Now solar panels can be expensive, can't they?

0:17:490:17:51

-Are they worth it?

-There's two sorts of solar panels.

0:17:510:17:54

The solar water-heating panels needn't be expensive

0:17:540:17:56

and they pay back very quickly.

0:17:560:17:58

For the panels that generate electricity, solar PV panels,

0:17:580:18:01

they do cost more to install, but because of the government

0:18:010:18:03

feed-in tariff you can start to see a return after seven or eight years.

0:18:030:18:07

After 20 years of that grant,

0:18:070:18:08

you'll see a return on your investment of maybe 10%,

0:18:080:18:10

better than a high street bank.

0:18:100:18:12

How does the feed-in tariff work?

0:18:120:18:13

The feed-in tariff is a government grant scheme.

0:18:130:18:16

It pays you for the electricity you generate off your own roof,

0:18:160:18:19

even if you use it all yourself.

0:18:190:18:20

And if you generate a surplus which is fed back to the grid

0:18:200:18:23

you get an extra payment as well.

0:18:230:18:25

So solar panels can save you money. But are they suitable for anybody?

0:18:250:18:29

If you've got a roof that faces north,

0:18:290:18:30

then I'm sorry but solar panels are not going to really going to work.

0:18:300:18:33

But if you've got a large south-facing roof, then yes,

0:18:330:18:36

solar panels are going to save you money.

0:18:360:18:37

It's important to point out that the panels need to be fitted

0:18:370:18:40

by a registered installer so you can get the grant.

0:18:400:18:42

But if you're planning to stay in a property for many years,

0:18:420:18:45

then yes, the payback period, you're going to definitely see a benefit.

0:18:450:18:49

And of course you'll get lower energy bills all that time as well.

0:18:490:18:51

Peter White, thank you.

0:18:510:18:53

Back now to antiperspirant deodorants.

0:18:570:19:00

Earlier, we put three stick products to the test

0:19:000:19:03

over their invisibility claims.

0:19:030:19:05

But what about the ones that promise to be long-lasting?

0:19:050:19:08

Time we put those to the test as well.

0:19:080:19:11

Yes, Sophie. For this test we've recruited two very brave volunteers.

0:19:130:19:18

They're both fitness instructors at this sports centre in Huddersfield

0:19:180:19:22

and they each do approximately the same amount of activity every day.

0:19:220:19:25

This is the moment we told them

0:19:250:19:27

that they wouldn't be able to shower for three days.

0:19:270:19:29

Oh, no! What?

0:19:290:19:31

Oh, yes. You'd better hope these products live up to their claims.

0:19:320:19:37

On his left armpit, Sean will be wearing

0:19:370:19:39

Triple Dry 72-hour antiperspirant.

0:19:390:19:42

And Adam will be wearing Right Guard Xtreme Fresh 72-hour antiperspirant.

0:19:420:19:46

On their right armpit they'll apply the most standard

0:19:460:19:49

mid-range product on the market we could find,

0:19:490:19:51

which claims to only give 24-hour protection.

0:19:510:19:54

Will the products claiming to last 72 hours

0:19:540:19:57

in reality last two days longer

0:19:570:19:59

than the product that only claims to last 24?

0:19:590:20:01

-This is going to get smelly.

-You bet!

0:20:010:20:04

So fast forward just under 24 hours.

0:20:040:20:08

It's almost been one day so we would expect both of the antiperspirants

0:20:080:20:12

to be working after one day,

0:20:120:20:14

so we'll see how they're doing, shall we?

0:20:140:20:16

Rather you than me.

0:20:160:20:18

No, that smells really good, really nice!

0:20:180:20:20

And the long-lasting one as well.

0:20:200:20:22

That smells great.

0:20:220:20:23

You're smelling good, still.

0:20:230:20:25

Fine.

0:20:250:20:27

Good, no, you both smell great, can't smell anything.

0:20:270:20:30

So it's still working.

0:20:300:20:32

Next, the vapour meter test.

0:20:320:20:33

This device measures the moisture that's evaporated from their skin.

0:20:330:20:37

On their forearms they measure about 10,

0:20:370:20:39

but let's see how their armpits are doing.

0:20:390:20:41

Starting with Sean's 24-hour product.

0:20:410:20:43

You have to wait 10 seconds.

0:20:430:20:45

There we go...178.

0:20:450:20:47

Eesh!

0:20:470:20:48

So that's quite sweaty already.

0:20:480:20:51

So let's try the 72-hour product to see how that's faring.

0:20:510:20:55

Ready?

0:20:550:20:56

163, so you are sweating under there, I'm afraid to say.

0:20:570:21:03

Next, Adam's 24-hour deodorant.

0:21:030:21:06

Right, that's 211.

0:21:060:21:09

That's a very high value.

0:21:090:21:11

And what about the 72-hour deodorant?

0:21:110:21:14

And it's 143, so it's high, but it could be higher, I think.

0:21:150:21:21

At the end of the first day... it seems the longer-lasting products

0:21:220:21:26

are working slightly better than the 24-hour product.

0:21:260:21:29

But let's see how the antiperspirants are doing

0:21:290:21:31

towards the end of the second day.

0:21:310:21:34

Once again, all products are performing well on the smell front,

0:21:340:21:36

even the 24-hour ones.

0:21:360:21:39

You know, you smell fine actually,

0:21:390:21:41

it's not too bad. Yeah, I thought it would be worse.

0:21:410:21:45

But according to Dr Laura's moisture test, after two days

0:21:450:21:48

the 24-hour deodorant is actually outdoing the 72-hour ones.

0:21:480:21:51

Which is quite surprising, really.

0:21:510:21:53

You'd expect them to be outperforming at under two days.

0:21:530:21:57

Day three. The final day of the test.

0:21:590:22:01

Will the deodorants which promise 72-hour protection

0:22:010:22:04

still be going strong?

0:22:040:22:06

So what we'll try first is the right side

0:22:060:22:08

which is the 24-hour product.

0:22:080:22:10

Now it's been nearly three days so it shouldn't still be working.

0:22:100:22:14

So do you want to have a quick sniff and see how you smell?

0:22:140:22:17

Yeah, will do...

0:22:170:22:18

-Yeah, that's definitely ripe!

-You can smell it? Right.

0:22:200:22:23

OK, and what about your left side?

0:22:230:22:24

That's the long-lasting antiperspirant. How does that smell?

0:22:240:22:27

Not too bad, actually.

0:22:290:22:31

So there is a difference between the two that you can smell.

0:22:310:22:33

How about you? Let's try your right side.

0:22:330:22:35

-Smells.

-You can smell it?

0:22:350:22:37

Yeah, I can smell it.

0:22:370:22:40

-And your left side, the long-lasting?

-Smells as well.

0:22:400:22:43

So after three days the boys are starting to smell,

0:22:430:22:46

at least under the armpit with the 24-hour protection.

0:22:460:22:49

But we're about to make matters worse.

0:22:490:22:51

How will they perform in what we're calling the ultra sweat test?

0:22:510:22:55

Dr Laura weighs these four cotton pads

0:22:550:22:57

and then tapes them under their armpits.

0:22:570:22:59

They'll each do ten minutes of exercise.

0:22:590:23:02

She then weighs the pads after they've finished.

0:23:020:23:04

The more sweat, the less the antiperspirants are still working.

0:23:040:23:07

First up, Sean, who's wearing the Triple Dry.

0:23:070:23:10

You were sweating more on the side

0:23:100:23:12

which was the long-lasting antiperspirant.

0:23:120:23:14

But for Adam it's the opposite result.

0:23:150:23:18

The 72-hour Right Guard was in fact stopping him

0:23:180:23:20

sweating more than the 24-hour one.

0:23:200:23:22

But overall, for both boys, there wasn't much in it.

0:23:220:23:25

According to our one-off test,

0:23:250:23:26

the 24-hour deodorants performed almost as well as the 72-hour ones.

0:23:260:23:31

Triple Dry have told us their products undergo rigorous

0:23:310:23:33

consumer and scientific testing that meet all relevant regulations

0:23:330:23:37

and they are confident in their performance claims.

0:23:370:23:39

Right Guard say they can't comment on the results of testing

0:23:390:23:42

that does not meet industry standards.

0:23:420:23:44

As for Sean and Adam, I think they would both agree.

0:23:440:23:46

If you're a fitness instructor,

0:23:460:23:48

whatever antiperspirant you're wearing,

0:23:480:23:50

better not leave it three days before showering, hey, lads?

0:23:500:23:53

Back now to second-hand tyres.

0:23:560:23:58

Earlier we saw how Trading Standards Officers in the Midlands

0:23:580:24:02

have been cracking down on garages selling illegal tyres

0:24:020:24:06

and removing them from sale.

0:24:060:24:07

It's time to find out just how hazardous they can be.

0:24:070:24:11

Potential dangers you find with part-worn tyres

0:24:110:24:14

are if they don't comply with the legislation,

0:24:140:24:16

Tyres can just explode, come straight off, cause fatalities.

0:24:160:24:20

Brian and his colleagues have so far inspected three garages

0:24:200:24:24

and found all of them selling problem tyres.

0:24:240:24:26

That is an absolute potential killer,

0:24:260:24:29

and the side wall has collapsed.

0:24:290:24:31

So we've got cracking towards the edge of the tread,

0:24:320:24:35

which is potentially catastrophic.

0:24:350:24:37

If that went on the road the tyre would leak,

0:24:380:24:41

and the nail would cause a blowout.

0:24:410:24:44

They're now on their way to the last inspection of the day.

0:24:440:24:47

Will it be four out of four?

0:24:470:24:48

We've got some experts with us

0:24:480:24:50

and we'd like to just have a look at your stock.

0:24:500:24:52

Because we're looking for any defects or problems

0:24:520:24:54

-that you might have missed when you were inspecting them.

-OK.

0:24:540:24:57

Sure enough, Brian spots a problem.

0:25:010:25:03

One of the tyres on sale has been badly repaired after a puncture.

0:25:030:25:07

To sell a tyre in that condition is illegal,

0:25:070:25:10

because it doesn't conform to the British standards of repair.

0:25:100:25:14

And none of the tyres on sale

0:25:140:25:16

is labelled with the "part-worn tyre" label that's required by law.

0:25:160:25:21

After a full day's inspection, all four garages visited

0:25:210:25:24

were found to be selling a number of dangerous and illegal tyres.

0:25:240:25:28

The team has reminded them of their duty to comply with the law

0:25:280:25:31

and will be carrying out further spot checks in the future.

0:25:310:25:35

We've examined round about 140 tyres,

0:25:350:25:38

part-worn tyres that is,

0:25:380:25:41

and there's been round about a third to 35%

0:25:410:25:45

that have been structurally defective,

0:25:450:25:48

and these are being fitted every day to people's vehicles.

0:25:480:25:51

So just how dangerous can tyres

0:25:520:25:54

like the ones found on sale in the Midlands be?

0:25:540:25:57

To find out, we've come here,

0:25:570:25:58

to the Motor Industry Research Association - MIRA -

0:25:580:26:01

one of the world's largest independent testing grounds,

0:26:010:26:04

where some defective tyres are going to be put through their paces.

0:26:040:26:08

What we're going to show you today is exactly what could happen

0:26:100:26:13

if you buy a part-worn tyre, so you will see the car handle

0:26:130:26:18

in wet conditions, or not as the case may be,

0:26:180:26:20

you'll see what will happen when one of those part-worn tyres fails.

0:26:200:26:24

The man behind the wheel is Steve.

0:26:240:26:28

The tyres that were seized all show serious damage.

0:26:280:26:31

This could have a serious impact on the safety

0:26:310:26:33

of whoever's driving the car at the time.

0:26:330:26:35

Two of them had bead damage, for example,

0:26:350:26:38

and one had penetration damage.

0:26:380:26:40

So any of these tyres could lead to a slow deflation on the car,

0:26:400:26:43

you could be running with a low tyre pressure, or worse still,

0:26:430:26:46

you could have rapid tyre deflation which is a serious safety issue.

0:26:460:26:49

So the first test, Driving a car with low tyre pressure.

0:26:490:26:52

Steve rigs this Ford Focus with four tyres he's lowered

0:26:520:26:56

to around 12 psi below the recommended level.

0:26:560:26:59

And he's ready to take it for a spin.

0:26:590:27:01

So what we've got here is a car that's been simulated to have

0:27:020:27:06

effectively part-worn tyres that have had a slow deflation

0:27:060:27:09

and this is going to show the seriousness of the handling

0:27:090:27:12

that might happen on a wet, slippery track like the one we've got here.

0:27:120:27:15

Here he goes.

0:27:160:27:17

The low tyre pressure has seriously affected Steve's ability

0:27:230:27:26

to control the car.

0:27:260:27:28

You can see the rear left tyre is wobbling on the rim,

0:27:280:27:32

and the car is sliding all over the place.

0:27:320:27:34

But there's worse to come.

0:27:350:27:37

If you're running at low pressure and you make a sharp turn

0:27:370:27:40

then the tyre can actually come off the rim.

0:27:400:27:42

This is a very scary thing that's going to happen here,

The car's going to slide forward, or maybe even spin,

0:27:500:27:52

and what's actually going to be touching the road is the rim

and not the tyre, and the rim has very little grip

0:27:590:28:01

and he was only travelling at 30mph.

0:28:220:28:25

0:28:250:28:29

the consequences could be devastating.
