This product is specially designed for safely cleaning and maintaining all butyl, hypalon, rubber and vinyl boats and surfaces. It slows down the ageing process considerably, prevents drying out and cracking and removes ingrained dirt, tar, diesel oil, scuff marks etc. Seapower Inflatable Boat Cleaner is also excellent for cleaning fenders. After treatment, they will not become sticky when exposed to sunlight, like other cleaners. Our cleaner also reduces fender squeaks, familiar to all who lie alongside.
