okay so im taking my tire off and right behind the pedals on the axle it is all dirty are there anyways i should clean this or what should I do to make it like clean again or what?
thanks to anyone who responds
Just wipe it off with a dry rag or a paper towel.
Don’t use anything like WD-40 to clean it off. WD-40 can actually wash away grease that is inside the bearing and you don’t want to do that.
