like anything around the house or cheap
kerosene or gasoline. Be careful.

Eh, boiling water should clean out the old grease. Soaking em in charcoal lighter fluid would work also the use a light and thin oil like cooking oil instead of grease with reassembly.
There are citrus cleaners on the market (you may have some around the house like Desolvit or Goo B Gone or some orange cleaner) which can be used for cleaning bearings with. Not all bearings are serviceable, meaning that you can remove the protective shield on one side. The ones that are usually have a rubber seal on one side and the other is metal. You have to pop off pin holding on the shield and remove it, then remove the ball bearings. You can drop them in the cleaner and wipe out the crud inside the housing, then dry them off good and allow to air dry then re-assemble. After that you'll need some oil or hi-speed grease to pack them with and put back together. For bearings that aren't servicable you have a couple choices, either oil them (which is messy and the dirt will stay inside, but they will be a little faster), or I think they sell some cleaner in a jar for about $8-10 you can drop them in which supposedly cleans them then you have to oil them. But I don't think it works that great Good luck
