Clean Sunbrella® Shade Fabrics

One of the best ways to keep Sunbrella 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.

When it's time for a thorough cleaning, Sunbrella fabrics can be cleaned while still on an awning frame or, size permitting, they can be removed to aid in the cleaning of stubborn stains or for professional cleaning.

General Or Light Cleaning

To clean Sunbrella while still on an awning frame:

  • 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.

See our Stain Chart for specific recommendations.

Heavy Cleaning For Stubborn Stains And Mildew

Sunbrella 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 quarter of a cup of mild detergent per 3.8 litres of clean water.
  • Allow mixture to soak into fabric for up to 15 minutes.
  • Clean with soft bristle brush. Note: This step should be avoided when cleaning the coated side (Back side) of Sunbrella Plus, Supreme, or Clarity.
  • Rinse thoroughly until all soap residue is removed.
  • Air dry.
  • Repeat if necessary.
  • Re-treatment of fabric for water and stain resistance will be necessary after using bleach solution.

Note: Use caution when cleaning the coated (underside) of Sunbrella Plus, Supreme, or Clarity with the recommended bleach solution. The coated side of the fabric should only be sprayed with the recommended bleach solution and then rinsed thoroughly.

Remember to protect the area around your Sunbrella if using a bleach solution. Carpet or other fabrics that are not Sunbrella may have an adverse reaction to the bleach.

Re-treating Sunbrella Fabrics

Sunbrella fabrics are treated with a proprietary brand of 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 re-treatment:
  • Clean Sunbrella fabric, using one of the cleaning methods.
  • Allow Sunbrella to completely air dry.
  • Apply re-treatment in a well-ventilated area following instructions on the container.

Professional Awning Cleaners

You may have access to professional awning cleaning firms. 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 re-treatment requirements.
