Have you tried Wheel Gerbil wheel brushes? They are back in stock and a HUGE customer favorite. The Chemical Guys Extended Reach Wheel Gerbils includes three sized brushes: Small, Medium, and Large to adequately clean every crevice and component of your car. The Large Gerbil Wheel Brush is the most plush to crawl in between large gaps within the spokes, to easily remove filth and grime, and especially harmful brake dust from the brake calipers, rotors, exhaust pipes, and fender liners. Use the Medium sized Gerbil Brush to get between intricate spokes, tighter grooves, hard to reach performance brake packages, and brake calipers. Use the smallest Wheel Gerbil Brush to detail the smallest components like lug nuts, valve stems, and multi spoke patterns with minimal wiggle room. The Extended Reach Wheel Gerbil Brushes by Chemical Guys possess the resilience, durability, and nimbleness to tackle any dirty wheel with the tenacity of a real life Gerbil!
