Sunbrella CanvasCare of Sunbrella

Sunbrella canvas boat tops can usually be cleaned while still on the boat. For underside and deep cleaning, removal and a large tub is recommended.

  • Brush or vacuum off dust and loose dirt. Prepare a mixture of 1/4 cup mild, non-detergent soap per gallon of water. Dreft is a recommended mild soap. Detergents will remove the waterproof coating from the canvas and are harmful to waterways.
  • Rub mix onto canvas using a soft bristle brush-the kind threaded onto a broomstick works quite well.
  • Allow the soap to soak in for a couple minutes.
  • Rinse off thoroughly. The hose works great.
  • Air dry.

Stains and Mildew

  • Prepare a mixture of 1/2 cup of chlorine bleach, 1/4 cup of mild, non-detergent soap and one gallon of water.
  • Gently scrub with a soft bristle brush.
  • Allow mix to soak in for up to 20 minutes.
  • Air dry.
  • Repeat if necessary.

Sunbrella canvas products including boat tops can be washed in a washing machine but only with cold-water wash and rinse. Never put them in a dryer. Air dry only. Water should be cool or tepid but never over 100 degrees Fahrenheit. Use only non-detergent soap such as Dreft. Routine cleaning can be done with the canvas on the boat or in a laundry tub for a thorough washing.

Sunbrella canvas is treated with a fluorocarbon finish, which lasts for several years but will eventually break down. You will notice this when water no longer beads together and rolls off the top but rather coats the surface. This finish coating will also be removed by washing with detergents. It is necessary to periodically re-treat this coating using 303 High Tech Fabric Guard-the only treatment recommended by Sunbrella. It will restore its water repellency and protects against oil-based stains.
