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

When it's time for a thorough cleaning, Sunbrella fabrics can be cleaned while still on the awning or boat, but size permitting, they can be removed for cleaning in a washing machine, too. When cleaning Sunbrella fabrics, it is important to observe the following:

  • Always use a natural soap. Never a detergent.
  • Water should be cold to lukewarm. Never more than 100 degrees.
  • Air dry only.
  • Never apply heat to Sunbrella fabrics.
  • Use 303 Fabric Cleaner
If you are cleaning Sunbrella canvas while still on a frame or on a boat, follow these simple steps:
  • Brush off loose dirt.
  • Hose down.
  • Prepare a cleaning mixture of water and mild, natural soap (no detergents).
  • Use a soft bristle brush to clean.
  • Allow soap to soak in.
  • Rinse thoroughly.
  • Air dry.
  • Apply 303 Fabric Guard.
If stubborn stains persist, you can use a diluted chlorine bleach/soap mixture for spot cleaning of mildew, roof run-off, and other similar stains. Here's how to prepare a special cleaning mixture:
  • Four ounces (no more than half of a cup) of chlorine bleach.
  • Two ounces (one-fourth of a cup) of natural soap.
  • One gallon of water.
  • Clean with soft bristle brush.
  • Allow mixture to soak in for no more than 20 minutes.
  • Rinse thoroughly.
  • Air dry.
  • Apply 303 Fabric Guard.
Repeat if necessary. If an awning or boat cover is suitable in size for a washing machine, these steps should be followed:
  • Use only natural soaps.
  • No detergent.
  • Wash and rinse in cold water.
  • Air dry.
  • Apply 303 Fabric Guard.
  • Never put Sunbrella fabrics in your dryer

Retreating the fabric canvas, as part of the finishing process, Sunbrella fabrics are treated with a fluorocarbon finish, which enhances water repellency. This finish is designed to last for several years, but must be replenished after a thorough cleaning. Based on test results, Glen Raven recommends 303 High Tech Fabric Guard as the preferred re-treatment product for Sunbrella fabrics. Fabrics should be retreated after thorough cleaning or after five years of use.

303 should be applied to Sunbrella fabrics after each thorough cleaning, which typically removes the original fluorocarbon finish and reduces the fabric's water resistance. After cleaning the fabric, allow it to air dry completely and then apply 303 in a thin, even coat. After allowing the first coat of 303 to air dry, apply a second thin, even coating of 303. Two light coatings are more effective in restoring fabric water resistance than a single heavy coating. The 15-ounce aerosol provides coverage of up to 50 square feet of lightweight fabric.

You may have access to professional cleaning firms that service awnings. In evaluating the services of a professional firm, you should inquire about a firm's experience in working with Sunbrella fabrics and knowledge of cleaning and retreatment requirements.
