- This is a $50,000 dry ice gun
and it can clean just about any part on your car.
That looks great.
Now, Justin and I both have our methods for cleaning gunk
off a car that are certainly cheaper, but are they better?
You're sweating.
- Yeah.
Is this high tech fog machine worth it?
Let's find out.
(ice crackling)

- Okay, so the absolute cheapest way to do this is
to get some degreaser, a brush, and use good
old-fashioned elbow grease to get this dirt off.
- So a bottle of degreaser concentrate'll cost you
your round $12, that's pretty cheap,
a brush, $2, water, should be free.
Degreaser may be super simple
but it's actually super scientific.
The molecules in degreaser have two sides.
One side is hydrophilic, so it sticks to the water.
The other side is hydrophobic,
so it likes to stick to the oil.
So once you scrub and rinse this all off,
it takes both things with it.
You're gonna wanna wear gloves
because this stuff is really strong.
(cheerful music)
- All right, Justin, well, that looks like
it's coming along pretty well, but it looks like
a lot of effort and I hate effort.
I got a pressure washer and it should be pretty easy.
You're sweating.
- Yeah.
- But I'm gonna be cool as a cucumber.
This is my pressure washer.
This one costs about 300 bucks.
It's a nice little electric unit.
You can get them for cheaper than that, less than $100,
but this is what we have
and it should make cleaning a breeze.
Not only does a pressure washer use a lot of pressure
but it uses water, which gets into nooks and crannies
really well, so it does a good job of cleaning,
you know, complex contours and surfaces,
like we've got on this valve cover,
without dispensing any elbow grease.
What I'm gonna do is spray this thing down with degreaser
to get a little extra action and hit it with a pressure
washer, and it should come pretty clean almost instantly.
Just throw some eye protection on
and pretty much ready to go.
You might get a little damp, though.
(exuberant music)
(camera operator shouts)
All right, that took me about 30 seconds,
how long do you think you took?
- About 10, 15 minutes.
- And I didn't break a sweat, although my feet are wet.
- Yeah, my forehead's wet.
- Let's compare results.
Looking pretty dang similar.
- Yeah, that looks pretty good.
- I would say your nooks and crannies are a little worse
than mine because the pressure washer's so good
at getting in those little tiny crevices.
- Exactly, that that goes to show with more effort,
I could have gotten a smaller brush
and got all that extra gunk out.
- Right, but it is more effort and more time.
- And I'm lazy.
- If you can afford a pressure washer,
it seems so far, that that's the way to go.
(whip cracks) (bell chimes)
(explosion bangs)
All right now, as far as cleaning actual engine bays goes,
degreaser and pressure washers are great for that task.
The only thing is you have to be careful a little bit.
You have to take some precautions.
Painted surfaces, like your paint on your car,
doesn't like degreaser.
It can cloud up the clear coat or kind of start
flaking it off altogether and pressure washers,
again, use a lot of pressure and a lot of water.
So you wanna be careful what you're spraying.
You need to cover up your alternator, cover up your air
filter and try to avoid directly spraying any
electrical components, especially any that are in bad shape.
And what I hear is that you don't have to use
any of that caution with a dry ice gun.
It's safe for use on painted surfaces.
It's safe to use on your air filter, your alternator,
and everything on the car.
Let's go blast some fricking ice.
(hood snaps)
(quick bouncy music)
All right, we're here at R20 Motorsports
and this is Matt, the dry ice man.
What can you clean with dry ice,
what can't you clean on a car?
- We can clean metal, we can clean plastic.
- Oh wow.
- Wiring, almost, you name it, we can clean it.
- And that's more versatile than I expected.
- We charge about $250 an hour,
so you're in the 250, 300 up to $500 for a car like this.
(fast music) (ice sloshing)
- All right, so to get us started, Matt's gonna show us
how to use this thing on the engine bay.
He's gonna go through and clean some stuff up,
probably blow our minds, and then we'll put the car
on the lift and Justin and I will take a shot
at cleaning some of the parts underneath.
Matt, let's see it.
(explosion thunders)
(fast exciting music)
(machine hissing)
- I mean, that's back to new.
- [Francis] Golly, that's awesome.
- [Matt] Dry ice cleaning has three simple properties.
The first is impact,
so you guys talked about sandblasting.
We are doing the same thing.
We're flinging a dry ice particle at the contaminant,
trying to remove it off the part.
The second thing is cold.
So dry ice is -109 degrees Fahrenheit.
So literally we try to freeze that part
and freeze the material.
It literally causes the dirt or the contaminant
to pop off the part.
And then the last piece is expansion.
So dry ice sublimates, it goes from a solid to a gas,
And when it does that, it expands by 800 times.
It's like a little mini explosion on the part.
- Fricking rad.
All right, let's throw this thing on the lift
and give the underside a shot.
Ready to get our shot at this thing.
The laser wasn't this friendly,
so let's see what we can do.
(fast clanking music)
- All right, so a lot of German cars come
with a substance on the underneath of 'em
and all throughout 'em, really, called cosmoline.
It's a waxy substance, and it's really just a protectant
for shipping across the ocean.
So it's kind of a grimy, ugly substance.
It's all this gold stuff you see
on the heat shields and it's sort of throughout.
And the dry ice does a really good job
of taking it off really quickly,
which is awesome for somebody who's a clean freak.
So let's see how well it does.
We're gonna pick some hot spots,
some stuff that'll shine up real nice, see how it works.
So first I'm gonna hit this here
sub-frame mount and see how it cleans up.
Exciting.
(machine hissing)
That's pretty cool.
And that was quick and this is fun.
All right, let's clean some other stuff.
(fast music)
What?
Well, that is both satisfying and addicting.
That looks brand new, I'm impressed.
(fast music)
- That's fun, that's a lot of fun.
(fast music)
It took no time at all.
It's just like sand blasting,
except it just preserves your materials.
It's just removing everything that's on top of it.
- [Zack] Okay, so obviously this thing cleans really well,
but we've been comparing it to a couple different products,
the laser and sandblasting, that actually can remove rust
by resurfacing whatever the material is.
Let's give this thing a shot on a nice rusty rotor
and see what it can do.
- It may not remove all the rust there.
I mean, this is a much softer process, made for cleaning,
but we can at least get it to a better condition
than when we started.
(leaping music)
- Well, sir, I'd say you undersold it a little bit.
- I was gonna say the same thing.
- Looks amazing and it worked
just as fast as that laser did.
- That's a pretty good surface rust.
If the rust was probably deeper in the middle,
- Yeah, a little more pitted. it's not gonna do it.
The laser's gonna take more off.
Sand blasting is gonna take more off.
- Well, that's pretty useful.
I mean, it does a great job cleaning dirt,
gunk and grime, and surface rust.
Pretty cool, but at $50,000 for the machine
or $250 an hour, versus our elbow grease methods,
what do you think?
Is it worth it?
- For broke car guys like ourselves,
It's not really worth it.
(deep chords boom) (bell chimes)
(explosion bangs)
But if you've got something really nice
that you wanna preserve-
- Exactly, so when the day comes that I got
a flip-up headlight NSX, I'm gonna dry ice the whole thing.
(deep chords booming) (static hissing)
In case you didn't know, Inglewood Propulsion
Laboratory is what we call our shop here in Inglewood.
Now I've been testing this hat out for a few months.
That's why it's so dirty, but it's working,
so we decided to release it.
So go to donutmedia.com to get yours today.
Right now, go, click it, best hat ever.
These coming soon, garage door is not for sale.
(lyrical music)
So if you're the type of person that does have
a really nice car and you do wanna do this,
there's something called Dryce, which is basically
a dealer network, so to speak, that helps you find
somebody in your area that does this on a level like this.
