I finally have a cleaner found the (etc brake dust, stains,) the dirt down gets gentle. Down wash wheels, spray cleaner (specifically in a rag spray), rub, let soak max.4min. If necessary, use a brush handle, then evaporate, as it does not come with wheels mounted in the interior of the rim and the brake disc, ready, Did then the wheels with a nanosealing versehen.Der dirt and the water seem to repelling water, times see how long the effect will last. The best product that I previously had for rims.
