One of the best ways to keep Sunbrella fabrics looking good and to delay deep or vigorous cleanings is to properly maintain the fabrics. This can be accomplished by simply brushing off dirt before it becomes embedded in the fabric, wiping up spills as soon as they occur, or spot-cleaning soon after stains occur.

- Always use a mild soap such as Ivory Snow, Dreft or Woolite.
- Water should be cold to lukewarm. (Never more than 100°F/38°C.)
- Rinse thoroughly to remove all soap residue.
- Air dry only. Never apply heat to Sunbrella fabrics.
General or Light Cleaning
To clean Sunbrella fabric while still on an awning frame, follow these simple steps:
- Brush off loose dirt.
- Hose down.
- Prepare a cleaning solution of 1 gallon of cold water with no more than ¼ cup mild soap (see above)
- 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.
- Re-treatment may not be needed depending on the age of the fabric.
- If stubborn stains persist, you can use a diluted chlorine bleach/soap mixture for spot cleaning of mildew, roof run-off, or other similar stains. Alternatively, a strong degreaser or Sunbrella ExtractTM Oil Based Stain Remover may be required. (see our Stain Chart for specific recommendations).
Heavy Cleaning for Stubborn Stains and Mildew
View the Sunbrella fabric Stain chart. Sunbrella fabric does not promote mildew growth, however, mildew may grow on dirt and other foreign substances that are not removed from the fabric. To clean mildew or other stubborn stains:
- Eight ounces (1 cup) of chlorine bleach.
- Two ounces (1/4 cup) of mild soap and/or detergent.
- One gallon of water.
- Clean with soft bristle brush.
- Allow mixture to soak into fabric for up to 15 minutes.
- 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.
Remember to protect the area around your Sunbrella fabric if using a bleach solution. Carpets or other fabrics that are not Sunbrella may have an adverse reaction to the bleach. If an awning is suitable in size for a washing machine, these steps should be followed:
- For heavier stains add 1 cup of bleach to wash.
- Wash and rinse in cold water.
- Air dry. Never apply heat to Sunbrella.
- Re-treating the fabric for water and stain resistance will be necessary after washing in a machine.
Re-Treating the Fabric
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 full cleaning. Based on test results, Glen Raven recommends 303 High Tech Fabric GuardTM as the preferred re-treatment product for Sunbrella fabrics.
Applying 303 High Tech Fabric Guard
303 should be applied to Sunbrella fabrics after each thorough cleaning, which typically removes the original finish and reduces the fabric’s water repellency.
- Clean Sunbrella fabric, using one of the cleaning methods.
- Allow Sunbrella to completely air dry.
- Apply 303 Fabric Guard in a well-ventilated area following instructions on the container.
- Apply 303 in a thin, even coat and allow fabric to dry completely.
- Apply a second thin, even coating of 303. (Two light coatings are more effective in restoring fabric water resistance than a single heavy coating. A 15-ounce bottle provides coverage of up to 50 square feet of fabric.) You can purchase 303 High Tech Fabric Guard at Kohler Awning.

DO NOT DRY CLEAN SUNBRELLA FABRICS OR SOLUTION-DYED ACRYLIC FABRIC.
Helpful Hints
- Protect the area around the Sunbrella fabric when using a bleach solution. Bleach may discolor non-Sunbrella fabrics. Always rinse Sunbrella thoroughly to completely remove bleach. The residue of bleach will lead to further mold growth.
- Sunbrella air dries very quickly. Machine drying is not recommended.
- If fabric has some wrinkling, use an iron, but only on the synthetic* setting. Caution, some irons exceed the recommended 100°F/38°C temperature on the synthetic setting, test a small, inconspicuous area before ironing the entire piece.
- DO NOT use a steamer or iron set to steam setting.
- Using bleach and/or the advanced age of the fabric may impact the deterioration of the sewing thread and other non-Sunbrella components.
When cleaning Sunbrella fabrics, it is important to observe the following:
- Always use a mild soap such as Ivory Snow, Dreft or Woolite.
- Water should be cold to lukewarm. (Never more than 100°F/38°C.)
- Rinse thoroughly to remove all soap residue.
