- Hey rust, are you ready to die?
Oh, hell yeah!
This is a $50,000 laser rust remover machine.
- Oh my gosh.
- That one will kill you.
- Is this laser really the best way to remove
rust off your tools and parts?
Today, we're gonna test a bunch of methods to find out.
Oh my God, look at that.
It's working!
Let's go.
- Big old thank you to eBay Motors
for sponsoring today's video.
- Hey Joe, what you doing?
- Oh, I'm just messing around with
this Universal Gator Grip Socket
to see how universal it really is.
By the way, did you know that eBay Motors
is one of the only websites
where you can buy parts,
cars, and tools all in one place?
I'm gonna go try to work on something.
- You'll see us using a whole bunch of tools this season.
And thanks to eBay Motors
we'll have links in the description below
so you can buy the exact tools we use on this show.
And if the tools you get aren't a perfect fit
eBay Motors has an awesome money back guarantee.
Which means you'll either get what you ordered
or your money back.
It's that simple.
Well, Joe, how universal is it?
- Check it out.
It even works on this bike.
Now show eBay Motors some support
by clicking the link in the description below
to shop tools and a whole lot more
including Donut merch
which is now also available on eBay.
- All right guys, I'm taking a half day.
I'll see you later.
- Well, hold no, don't take that bike.
- No, no!
(crashing noise)
My sweet baby boy.
Here, I can fix that.
- Now, before we get to the laser, Joe
we gotta talk about rust.
So what is this stuff?
- Oh rust is a cancer like no other.
I hate rust so much.
That's why I moved to Southern California.
- Yeah, we don't have it here.
We had to ship these tools in
from the South.
- So today we've got some rusty tools here
that we're gonna try to unrest
using five different methods.
From bare bones,
wire brush up to a $50,000 laser!
- Insane.
So our first method is using abrasion
and some muscle, AKA elbow grease.
- Good thing I'm here, dude.
- How about we start off with, I don't know,
probably the cheapest of this.
- Ah, my toothbrush.
- So we'll test our wrench.
You can tell that there's some pitting,
which is irreversible.
That's the problem with rust.
Once it starts pitting and taking away that iron
it's gone forever, you're never putting it back.
But we can clean this surface stuff up.
- How's that feel?
- Sometimes you gotta wet it a little.
Well we're lubing it up.
- I did not see that coming.
- I know.
- Hey, look at that.
- Yeah great.
That looks pretty good.
- Yeah, use some Scotch-Brite.
You're getting a fingy workout.
- Oh yeah, dude.
But luckily I got strong fingers.
- Oh.
- You know, I think the brush did a better job
of getting into the like kind of pits.
But the pad did a nice job overall.
- So let's use the most aggressive method.
- Yeah, we got a power tool here.
- And your finger can just last all day long.
(power tool whizzing)
- Well I'll be a baby's bottom.
- Yeah, that's not too bad,
but I'm gonna go ahead and say
that it really didn't do much
better than just the bristle brush.
We also did get a little bit of damage.
- Look at that.
We did what?
Maybe seven minutes of work.
We went from this, to that.
- Much better.
But also I think that we could
probably get a better result.
Let's turn up the abrasion.
Turn down the grease.
- Media blasting.
- Heck yeah, man.
- We got ourselves a little media blasting
set up for about $70 altogether is $35
for the media blaster itself.
And then about 30 bucks for the media.
You do need a pretty good compressor,
but if you have one,
this is a great way to remove rust or paint
or pretty much anything that's on top of a metal surface.
You can use a lot of different types of media
that suit the thing that you are blasting best.
So today we've got a glass bead.
Basically a sand and that's gonna be
one of the most aggressive.
We've got some sand in the tank.
We got some air in the tank over there.
- We're ready to rock.
- Do it.
Let's see how this goes.
- Nice box.
- Thanks man, everybody says that to me.
(power tool blasting)
- Whoa.
- Oh wow.
- Oh my God look at that, it's working.
- It's working.
- Whoa, that's pretty good Joe.
- Yeah, not too bad.
After just a couple minutes and very light effort.
- And it's getting down to the bare metal.
Another positive thing when you use a sand blaster.
- Yeah, it's full step further I would say.
It just is a little bit messy.
- You did that for maybe two minutes.
- It's true.
- And look at this.
- There is sand everywhere.
(shoes squeaking)
- Yeah, but you can do that without sand dude.
I've seen it.
- All right, Jerry well, you did a great job
media blasting that big old wrench.
Tell us about how it looks.
- So far it's done the best job.
- Yes, easily.
- This is...
- What we did with the wire wheels and the steel wool.
- You still have pits in there.
You still have black oxides there.
This side.
- This side that's fresh.
- That fresh steel.
- More expensive than the other methods,
but not bad at about $70.
It does make a mess however.
- Makes a complete mess.
- All right, now let's see
how our next method does- chemical.
All right, Jerry.
So what do we do if we got some rust,
but we don't feel like scrubbing it?
- You just wanna set it and forget it, right?
Well, luckily there's some smart guys out there
who made some chemical, like a CLR.
- What's that stand for?
- Calcium, Lime and- Rust.
- Now CLR, I remember seeing the infomercials.
Yeah, they make some claims.
- They make some claims.
- [Ad Presenter] CLR works all over the house.
It's guaranteed or your money back.
- This says you only need to let it sit for two minutes.
Which seems insane.
- Two minutes?
- So we're just gonna drench this wrench.
- Drench the wrench.
- I gotta tell you, Jerry, I'm skeptical.
I think at best it's gonna do okay
with this surface rust on the breaking face of the rotor.
- Well, let's put it in there.
- Oh, and we've got this thing.
- Yeah, so we found this at the racetrack.
I don't know what it is.
If you can identify what this.
- Yeah, I would like to know.
- Leave a comment down below.
There's two of them that we found next to a differential.
Take a good look.
- I thought you were farting, it's that.
- No, it's that.
- It smells terrible.
Because then I was like 'wait, did I fart?'
- Oh, yeah it is kind of farty dude...
Okay, let's wait two minutes.
There you go.
- [Producer] Can you do one more
where it's not so ****in' weird?
- Yeah, let this sit for two minutes
and see what happens.
- That's 120 seconds.
Two minutes,
Two, three.
- Wait, two minutes.
- Okay, now let's wait two minutes.
- [Producer] It's been more than two minutes by now.
- Has it?
- Pull this thing out.
- Wow.
- Yeah, we got some surface rust
that's gotta come off there.
Better than I expected.
Well, I'll be darn too.
- And shall we do a wipe?
- Yeah, gimme a wipe.
Well this is like a Bounty commercial.
- Wow.
Fresh metal, old rust on the backside.
We've got a little bit more pitting.
It made it better,
but you can see we've got clean, clean, clean
and then the pitting starts.
It didn't manage to do much about that.
Now this was definitely the worst rusted bit.
- Okay, I mean obviously rust is coming off.
- Yeah, sure.
- Yeah but like, like compared to this?
- Well, yeah and I think that is
the difference between the deeper rust
and the more surface level stuff.
Another nice thing about the chemicals,
especially on something like this,
we've got all these little textures,
the grooves here, that's a lot harder to get into
with the wire wheel.
But the chemicals get in everywhere.
All right, now, should we kick this up a notch?
- Yeah, I think we should.
I think maybe adding a little bit of mechanical advantage
to chemical would be like the perfect mix.
- Like the best of both worlds.
All right, Jerry, what the heck is this thing?
- This is a digital ultrasonic cleaner.
- Whoa, that sounds fancy.
- Yeah, so ultrasonic means that
it use high frequency sound waves,
ultrasound to create small little bubbles or capitations.
And when those bubbles pop, they disrupt
the surface of the part and they clean it.
- All right, now how much does little puppy cost?
- This thing is about $200.
This is a bigger one.
Pretty much anything that can
fit inside, you can clean.
Instead of filling the entire tank,
cool little trick which you can do is
get some sort of glass jar
and just fill the glass jar with your solution
and then fill this with water.
- Way cheaper.
- So you can have all sorts of different chemicals,
different parts in this running at the same time.
- Rust doesn't stand a chance.
- It doesn't.
(electronic buttons beeping)
10 minutes.
Three, two, one.
(machine whizzing)
- Wow, it sounds awful.
- Whoa.
- Whoa, that looks grosser,
which means it must have worked.
- Oh, it's really hot.
It's 140 degrees.
- I smell that fart juice.
- I smell this juice.
- Whoa, dang.
- That's pretty dang good, man.
- That's really dang good.
That's a bunch of small cracks and crevices
that are kind of tough to get into.
And that's like turned it back to black for the most part.
- I don't see a ton of negatives with this.
- No, that's pretty good.
- Yeah.
- It smells bad.
- And not all chemicals are
environmentally safe or friendly.
- That's true.
- CLR is.
- But some you have to dispose of accordingly.
Take it to a place that actually dispose of that stuff.
Either way, when you start using any chemicals,
you're signing up to deal with the chemicals
once you're done with them.
- Right.
- What's next?
- Well, next we're going to use some electricity.
- Ooh, laser time?
- No.
- Okay, well then what is this?
- We have an electrolysis setup.
- Sick.
- We got a couple of things going on in here.
The first is we have a tank full of water.
And in this tank we have sodium bicarbonate,
which is also baking soda (*washing soda)
that allows for current to flow
through this whole system.
So we have a little simple set up here.
We have a battery tender.
- My grandpa's old battery charger.
- Yeah, Yeah.
Joe brought this all the way from Ohio.
We have copper wire,
which is a good conductor of
electricity and current.
We've wrapped them all.
So they're all getting very good contact
with our battery source and then we have it
clamped on over here, positive negative.
And when you put current through water,
splits water into hydrogen and oxygen.
So on this side we have oxygen,
which is bubbling up on this.
And on this side we have hydrogen gas,
which is bubbling up.
That hydrogen gas is reacting
with this metal on this wrench
and it's pulling the rust off.
We've been running this thing for about 24 hours now.
So we're gonna pull it out and see what it looks like.
- Well, Jerry, this is a pretty cool setup.
I can't lie.
♪ Jerry and Joe the science guys ♪
♪ Jerry and Joe ♪
♪ The science tool guys ♪
♪ Tools ♪
- Whoa, well, that looks pretty freaking good.
- That's a fresh rotor dude.
- Interesting markings left behind from the rust.
- Because it's a chemical reaction
changes the color of it,
but all that can be cleaned up.
- Yeah, it doesn't look like rust
and that's what's important here.
- And honestly, I would say this is way cheaper
than the ultrasonic cleaner.
- Right, because you probably have
a battery charger at home.
You probably have a tub.
It doesn't have to be a fish tank.
- It could be a five gallon bucket.
- And it's cool as hell.
- I mean, your mom comes in seeing this.
She's gonna be like, 'uh oh I got another unabomber.'
- Okay, is it laser time?
- Oh my God, Joe.
It's laser time!
- You may have seen on Instagram,
a bunch of people rust removing parts with the laser.
Well, we came to the source of these lasers
to test it for ourself.
The way these machines work is pretty interesting.
They use lasers to heat up the contaminants
on the surface of the part
and these machines can control how abrasive they are
depending on the amount of rust
or contaminants that you're trying to remove.
I also have Justin here because Joe has diarrhea.
He doesn't wanna talk apparently.
- Unfortunately we don't get to play with it but...
- Yeah, we're not certified in this
so we're gonna have a technician come,
but we'll be over here ooh'ing and aah'ing
and looking cool as hell, dude.
So first we're gonna start with this
200 watt pulse laser, which is less abrasive.
And then we're gonna switch over to the
1500 watt continuous laser,
which should be way more powerful.
And it's just gonna wipe all this stuff right off.
- It's gonna rip it apart.
- Prepare for some laser violence.
- Yeah, later rust, you *****!
- Goodbye!
Oh, here we go.
(laser whizzing)
- Oh ****, it's smoking it!
(laser whizzing)
- It smells good.
Can I touch that metal?
Is it hot?
- [Sun] Yeah, it's not hot.
Oh, oh wow.
What?
Wow.
- Oh nice and smooth.
- I'm excited to see what it does to this thick rust
because that nice sheet metal rust is one thing
but this is what most people deal with.
- Right.
(laser whizzing)
- Oh man.
That's brand new you can resell that thing.
(laser whizzing)
- Yeah, that's all break dust.
- That's enough fun and games with this little baby
200 watt thing, let's get to the 1500 continuous laser.
Let's have some real fun.
- You ready?
- Let's do it.
- Oh, hell yeah.
- That's cool.
- You can feel a heat coming off it.
- Oh man.
- Oh my God.
- That one will kill you.
- Yeah dude.
(laser whizzing)
- Dude that was cool as hell.
That one gets warm.
- Yeah, that one gets a little warm
but dude see all the scaling that it took off.
- Who needs to get their rotors turned.
- Dude, that's amazing.
All right, we saved our rustiest wrenches
and this thing which we don't know what it is,
but if you can tell us in the comments, that'd be great.
(laser whizzing)
- It's cleaning the floor.
(laser whizzing)
Heck yeah.
- All right cool let's try this one.
- Dude, that was great.
- Holy crap.
- Oh wow.
Oh that looks brand new.
- Dude, it's like kicking it off.
- It got in the teeth and everything.
- Oh dude, that's amazing.
You know, obviously with an intricate part like this
they're little small gaps in spaces
and to do that with a more traditional method,
like a wire wheel would be almost impossible
because you physically can't get down
in between those small nooks and crannies.
But you know what can get down there?
Light.
(laser whizzing)
- Dude, it's just ****ing toasting that paint.
(laser whizzing)
- Mesmerizing, I just keep looking at it,
which is why you need these.
- All right, Jerry.
So it looked like the laser was pretty dang cool,
but that's not really reasonable for anybody
trying to derust their car parts.
- Right, it's a more of a service
where a shop will buy that.
- Let's go over the methods that we went through
that you could actually do at your house.
- Right, so our cheapest just takes a little bit of muscle
is just using elbow grease.
- Far and away the worst that we tested today.
- Right, yeah it doesn't nearly do as good of a job
or quick as a job as some of these other ones.
- That's right.
- We're lazy bums.
- That's true.
- Unless you have a proper sandblast setup,
the way we sandblasted it, absolute mess.
- It was a huge mess.
- It works really, really good.
- That's true.
But the thing about a sandblaster or a media blaster
that stands out to me is that
you aren't beholden to the size of your tank.
It can do big things because you're just out there spraying.
You can do a whole car if you want.
You can do the frame of a car.
But if you're doing smaller stuff,
I mean the ultrasonic and the CLR, sick.
- Great, really fast.
It costs a little bit of money,
but you can do all sorts of parts.
It's not just rust remover,
if you got a gunked up carb, you can-
- Even, yeah, and you don't have to take the carb apart.
- Right, which is awesome.
All very cool technologies to remove rust.
- True.
- You know what?
We're all just fighting entropy Jobe.
- That's right, we're all oxidizing.
- We're all just falling apart.
And we're trying to prevent mother nature
from just breaking us down.
- That's right and luckily now
we've got a bunch of ways to do it.
- That's right.
We can fight back mother nature with ****in' science!
- Yeah **** you!
- Yeah, no don't say that.
- No, I love mother nature.
- Yeah mother nature, yeah.
- You also give us life!
- We just got our new Buff Horses Club tees
and they're super high quality and a hundred percent cotton.
Jeremiah already pulled an entire
motorcycle engine wearing it.
So you know, it's been tested.
Go get yours today at donutmedia.com.
- Thank you guys so much for watching.
You wanna see us continue this show,
put a comment down below we got some other tools
that you wanna see us test.
- Yeah, please give us some more ideas.
- Yeah, we love making the show.
It's one of the best parts of my job.
I love being here with... all these guys.
These guys right here, I love you.
(speaker laughing)
- Yeah, no he meant to say 'and me.'
He likes me I swear.
