Roll-Off Cleaner & Stain Remover works with water to clean almost anything. Spray on and dirt rolls off. Developed for tough boating stains, ''ROLL-OFF'' will amaze you with itâ€™s cleaning power. Dirt that other cleaners canâ€™t touch simply rolls off with little or no rubbing. A little goes a long way. Surfaces remain clean longer. Cleaning takes less time and can be done less often. Surfaces are left with a gleaming and rust-inhibiting wax-like finish. A biodegradable, non-acid product.
