I'm trying to clean out an old longboard I got for free from a friend, its full of rust and dirt. To clean the bearings and any other metal parts, I used to use rubbing alcohol, followed by Bones speed cream. I was out of rubbing alcohol this time around, so I soaked the bearings in De-Solv-It Contractor's Solvent, which I found in my garage, and plan to use speed cream on them once they've dried after the solvent. What do people think of this method? Is there a better way to get rust/dirt (the black stuff) out of bearings?
I have two bearings that won't turn almost at all, only pushing a little after a lot of force is applied to them, obviously they're rusted out more than this method can fix. Any way to make these work again? Or is there any appliance, piece of equipment, or anything house or garage item that uses ABEC bearings? I'm pretty pressed for money right now, so I'd rather try and salvage bearings than buy new ones.
