does anybody know what the best liquid to use for cleaning bearings?
Unless you plan on throwing your bearings out the next day, DON'T USE WD-40. I would suggest 90%+ Rubbing alchohol, but if you can't find that, 70%+ is alright, but it could kill your bearings, but its not a big chance.
I don't really know but i use rubbing alcohol. I would have alcohol in a cup and put my bearings in then with my top hand cover the top and shake a little. Then take em out and roll em until they feel like they're new again(sorry for bad english im mexican)
