How to Clean

CLEAN MARINE CANVAS

One of the best ways to keep fabrics looking good is to hose fabrics off on a monthly basis with clear water. This helps prevent dirt from becoming deeply embedded in the fabric and eliminates the need for more frequent vigorous cleaning. In most environments, a thorough cleaning will be needed every two to three years.

General Or Light Cleaning

To clean the cover while still on a boat, follow these simple steps:

  • Brush off loose dirt.
  • Hose down.
  • Prepare a cleaning solution of water and mild soap such as Woolite or Dawn dishwashing liquid.
  • Use a soft bristle brush to clean.
  • Allow cleaning solution to soak into the fabric.
  • Rinse thoroughly until all soap residue is removed.
  • Air dry.
  • May not require re-treatment depending on the age of the fabric.

If stubborn stains persist, you can use a diluted bleach/soap mixture for spot cleaning of mildew. For roof run-off or other similar stains a strong degreaser may be required.

Heavy Cleaning For Stubborn Stains And Mildew

Our fabrics do not promote mildew growth, however, mildew may grow on dirt and other foreign substances that are not removed from the fabric. To clean stubborn stains:

  • Prepare a solution of 1 cup of bleach and one fourth cup mild soap per gallon of clean water.
  • Allow mixture to soak into fabric for up to 15 minutes.
  • Blot stain with a sponge or clean towel.Note: 
  • Rinse thoroughly until all soap residue is removed.
  • Air dry.

Retreating Fabrics

Our fabrics are treated with a proprietary water and stain repellent finish that is designed to last for several years, but may require replenishing after a thorough cleaning. Glen Raven® recommends 303® Fabric Guard, available in the United States, and Tex’Aktiv, available internationally.

Applying a retreatment:
  • Clean fabric, using one of the cleaning methods.
  • Allow cover to completely air dry.
  • Apply retreatment in a well-ventilated area following instructions on the container.
