Boat Vinyl Care

Vinyl Covers and Enclosures

Marine 31 vinyl cleaners and protectants ensure your boat's vinyl surfaces look and feel newVinyl seats and covers on a boat are susceptible to drying, fading, and cracking. The sun, water, and regular wear and tear all age vinyl. Any vinyl on or in your boat should be regularly cleaned and protected to maintain it over the service life of our boat.

The worst enemy to vinyl is extended exposure to the sun's rays and dirt and grime build-up. UV rays from the sun fade and dry vinyl out. Dirt and grime retain moisture on the surface and together cause the protective topcoat on vinyl to deteriorate. The best thing you can do to maintain vinyl is to clean it with products that won't harm or remove the topcoat on vinyl. Then apply a UV protectant.
