What do you guys clean your tires and wheels with to remove the dirt buildup and stuff? I tried some degreaser with paper towels, but it took like 40 paper towels to clean them all. And if I use a towel it stays black even when I throw it in the washer. Same with a brush and sponges. Is there something I can use to wipe them clean better without using too much of something or having it stain black?
