This is the standard wash mop used everywhere: in car washes, dealerships, detail shops, for the last 25 years. Some things you can't improve! Mophead is 100% soft cotton chenille fiber, 7"x7.5". The lightweight aluminum handle is the perfect length at 48", not too short or too long. It has 2 rubber grips. The rubber backing pad for the mop head will move with the contours of the vehicle. Mopheads last a long time, but when you need a replacement, the number is 85-331.
