How To : Cleaning Sunbrella Awning Fabrics

How To : Cleaning Sunbrella Awning Fabrics

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 fabrics, wiping up spills as soon as they occur or spot cleaning soon after stains occur.

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 for cleaning in a washing machine.
When cleaning Sunbrella fabrics, it is important to observe the following:

Always use a mild detergent such as Woolite or Dawn dishwashing liquid.
Water should be cold to lukewarm.
Rinse thoroughly to remove all detergent residue.
Air dry only. Never apply heat to Sunbrella fabrics.

General or Light Cleaning
To clean Sunbrella fabric 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 detergent 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/detergent mixture for spot cleaning of mildew, roof run-off or other similar stains.
See our Stain chart for specific recommendations.
Heavy Cleaning for Stubborn Stains and Mildew

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 stubborn stains:

Prepare a solution of 1 cup bleach and 1/4 cup mild soap per gallon of clean water.
Allow mixture to soak into fabric for up to 15 minutes.
Clean with soft bristle brush.
Rinse thoroughly until all detergent residue is removed.
Air dry.
Repeat if necessary.
Re-treatment of fabric for water and stain resistance will be necessary.

View the Sunbrella fabric Stain chart.

Remember to protect the area around your Sunbrella fabric if using a bleach solution. Carpet 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:

Use mild soap.
For heavier stains add 1 cup of bleach to wash.
Wash and rinse in cold water.
Air dry. Never apply heat to Sunbrella.
Re-treatment for water and stain resistance will be necessary after machine washing.

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 a thorough cleaning. Based on test results, Glen Raven recommends 303 Fabric Guard™ as the preferred re-treatment product for Sunbrella fabrics. Fabrics should be re-treated after thorough cleaning or after five years of use.
Applying 303 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.)
Note: A 15-ounce bottle provides coverage of up to 50 square feet of fabric.
