How to clean wheel bearings??

I take the old bearings and place them in a plastic bag. I then place the bag in the trash, open the boxes the new bearings are in, rinse them with brake cleaner and pack. By the time you purchase the solvent, dispose of the solvent and all the other trouble involved with cleaning the bearings you are almost in to new bearings. Actually I need to modify my instructions. I always have a set of bearings and a hub ready to go for all my trailers. I replace one hub assembly and then clean the other hub and install the new set of packed bearings. Why a spare hub? If I have a bearing failure on the road I can replace the hub almost as fast as I can change a flat tire and then replace the failed bearings at our next extended campground stay. I will always have a minimum of one complete ready to go hub when I am on the road.
