Everytime I clean the tires on my car, they come out brownish after they dry. I have been using EO wheel and tire cleaner on my tires using a medium-stiff bristle brush. I always dilute the EO cleaner with a little water, because my wheels are never dirty enough that I need the full cleaning power the EO, because it is strong stuff. What I don't get is that thorughly scrubbing the tires with the EO while using the brush, they seem to come out brown after I let them air dry. I can't stand looking at brown tires! I am wondering if I am using the wrong type of brush or I am doing the wrong procedure for cleaning them? Please help me out here
