Meguiar's Extreme Marine Multi-Surface Cleaner quickly removes dirt, grime, black streaks and grease from many marine surfaces, including vinyl seating, canvas, outboard motors, and non-skid, fiberglass and gel coat surfaces. The safe yet effective formula can be applied by spraying onto a towel and wiping, or spraying and scrubbing with a brush, followed by rinsing away. Use it to make seating surfaces like new, remove streaks from fiberglass and even remove stains from carpet. Extreme Marine Multi-Surface Cleaner is an excellent first step for deep cleaning vinyl and rubber, followed by Meguiar's Extreme Marine Vinyl and Rubber Protectant.
