Cleaning a bearing with acetone.


#1

I went to walmart today, and i saw acetone so i picked some up. I actually do have a bearing that needs cleaning though. Anyway, i went online to see how to clean a bearing, and i came across this .

I’ve read at many places that acetone is their favorite thing to use to clean a bearing, but now I’m not so sure. This is the acetone that I got:

Will the bearing be ok if i clean it with this?


#2

Yup, just put it in a jar or bottle, unshield the bearing, put it in the jar or bottle or a few minutes. You could shake it too. Then after a few minutes take it out, spin the bearing a bit and let it dry.


#3

Ok thanks!


#4

Just want to hear other peooles opinions too.


#5

yes. Mineral spirits is usually the preferred option because it’s less dangerous, but acetone works as well. I cleaned skateboard bearing (which get a lot dirtier than yoyo bearings) using fingernail polish remover for years, which contains a percentage of acetone.


#6

Acetone is absolutely fine. It’s the recommended solvent of the terrapin guy for bearings. (though you should be careful with acetone and ceramic bearings. Acetone might damage ceramic bearings)


#7

Are CTs ceramic?


#8

Nope.

A bearing being ceramic is typically a strong selling point, so if the bearing is ceramic, you would probably have been told it was ceramic when you bought it.


#9

ceramic is actually more resistant to chemicals than steel is.


#10

Ok i think I’m going to do it tomorow. Tonight I’m going to watch a whole bunch of how to videos first.

It’s pretty difficult to mess up cleaning a bearing. Just take off the shields, dunk it in some solvent, swish it around a bit, then take it out and let it dry.

You don’t even have to put the shields back on. Most people don’t.

You learn something new every day.

The reason I said might is because a few years ago cleaning a ceramic bearing with a solvent was considered harmful to the bearing. It was probably just one of those rumors that get spread around without any actual evidence. But, I thought I’d play it safe.


#12

I’m going to use pliers to swish it around.


#13

it’s fairly simple.

  • Deshield
  • Put in solvent
  • stir it around (or if it’s an air tight case, shake it up) for a while. maybe a minute or two
  • take it out
  • dry it. I usually set it on a paper towel, dry it a bit, then stick it on the end of a 1/4" rod (1/4" is the inner diameter of a c size bearing. the back of a drill bit works nicely) or pen or something that it fits snugly on, and spin it dry.
    And that’s it. I don’t reshield mine, don’t put any lube, just put them back in the yoyo and play. I’ve been running all my bearings dry like this for 2 years, and I have no problems with any of them. You can lube and reshield if you want to though.

I usually just use my YYF multitool to spin my bearings (after i lube and stuff)


#15

whatever floats your boat… but yea cleaning a bearing is super easy, you dont need to spend the night watching how to videos :smiley:


#16

I think most people were incorrectly cleaning their bearings and looking to blame something. I have a few ceramics, and while they don’t seem to be anything special or amazing to me, they clean up just fine with acetone.


#17

The old YYN store description for the ceramic KK bearing said it was recommended to just blow out the bearing, not clean or lube it. I think that’s probably where the “harmful” thing stems from.


#18

You’re way over thinking this.


#19

Ok. Im going to do it tomorow because i don’t have a glass container yet. My little sister’s baby food comes in a little glass jar, so after she eats tomorow my mom sais that I can have the little jar.

you don’t even need a glass container. I usually just use a plastic bowl or cup.
