Cleaning wheel bearings
What type of solvent or name of a product should I use to clean the wheel bearings and wheel axle? Is gasoline ok? I think there must be something more effective or safe. I have taken the main tires and wheels off to rotate the tires and there is brake dust on the bearings and axle that I want to remove.

Gasoline would be my last choice. For bikes, I used brake cleaner. I just hate the smell of gas and the blowing up part too.

I use mineral spirits. It does not dissolve the grease as fast as gasoline, but is safer. Compressed air is good to blow off the old grease and dry the bearing but be careful spinning it, the cage can expand and/or explode. Just be sure to use fresh for the last cleaning.

100LL. Works great, readily available, dries fast, it's the all purpose cleaner. Probably not a good idea to smoke while using it tho.

Mineral spirits, a throwaway cake pan, and an old toothbrush.

Wipe with paper towels. Spray with brake clean. Rinse with mineral spirits. Inspect. Re-pack with Sta-lube boat trailer grease from Napa Auto parts..... touch it and you will understand.

Nothing
I've read here that you shouldn't use a solvent. Simply pack with new grease until all the dirty grease is pushed out.
That's what I've done for three years now.

I've never cleaned mine. I inspect the race. If it's good, I inspect the bearing looking for any shiny flakes. Then I use a bearing grease packing tool and inspect the old grease that is forced out. If all is good, back in they go.

NEVER spin a bearing with compressed air. If it is not packed with grease, you will put more wear on it in a few seconds than a lifetime of normal use.
As said before, just pack in new grease until the dirty grease is expelled.
