The 10" wash brush has fine polystyrene bristles with fluffed edges to hold water and cleaning solution for easier washing, while treating your vehicle with kid gloves. The 10" Scrub Brush provides extra firmness needed to remove stubborn streaks from dirty areas on your vehicle that don't require the kid glove treatment. Adjust-A-Brush lightweight handles are made from premium grade drawn aluminum tubing with vinyl non-slip hand grips. The tubing is anodized to prevent corrosion. The handles attach to a standard garden hose and have a built-in water control system. Available in telescoping flow-thru and telescoping and non-telescoping handles.
