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 .
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.
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.
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)
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.
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.
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 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.
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.
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.
