The Red Rocket Brush is a gentle, flexible brush that can bend to deep-clean all those hard-to-reach areas around your car. With two different sizes and a unique bendable spine, there is no place for dirt to hide. Bends For The Deepest Clean Possible The innovative Red Rocket Brush uses a unique flexible spine that allows you to clean even the most inconvenient areas. Simply bend the brush to the desired angle, or insert into any small space and let the brush flex and conform to scrub 100% of the surface. Use the 9” brush on wheels, rims, brakes, and the smaller 5.5” on grilles, vents, exhaust pipes, and more. Sensitive On Your Wheels—And You Red Rocket Brushes feature rubber tips and rubber-wrapped spines to protect your wheels from any abrasive contact. The soft bristles of the brush are sensitive enough for any painted or polished metal wheel, yet durable and made to last. The knuckle guard helps protect your hands from painful contact with hard metal surfaces, allowing you to safely get the deepest clean possible.
