Have used until now even the rim brush. I get to all necessary places with my "Winteralus". First, I have the rims cleaned properly with water. After treated with Xtreme Rim Cleaner and brushed with the brush the brake dust and usual stubborn dirt. The dirt went down great. The Brush seems to be very stable, best treated with light pressure. The article is good, but not absolutely necessary. Do not regret the purchase.
