For dead black wheels, use hot water, about a third of the bottle of dye, and leave them to soak overnight.
I used the rough side of a sponge and got all of the scuffs off, the white urathane is just a little tinted yellow. I used more like 2/3 of the bottle instead, but I don't think it will make too much of a difference because it's not like black can be too black right? haha
