One of the best ways to keep Sunbrella fabrics looking good is to hose fabrics off monthly 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 a boat or, size permitting, they can be removed for cleaning dock side.

General or Light Cleaning

To clean Sunbrella 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 retreatment 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 Cleaning Guide 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 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: This step should be avoided when cleaning the coated side (back side) of Sunbrella SeaMark.
  • Rinse thoroughly until all soap residue is removed.
  • Air dry.

Note: Use caution when cleaning the coated (back side) of Sunbrella SeaMark with the recommended bleach solution. The coated side of the fabric should only be sprayed with the recommended bleach solution and rinsed thoroughly.

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

Retreating Sunbrella Fabrics

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

Professional Cleaners

You may have access to professional cleaners. In evaluating the services of a professional cleaner, you should inquire about a their experience in working with Sunbrella fabrics and knowledge of cleaning and retreatment requirements.

Helpful Hints


While Sunbrella fabric offers excellent protection against stains, full removal is not always guaranteed if spills are not addressed promptly.

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.

Please be aware of the environment when cleaning with bleach. Bleach can have harmful effects on the natural environment around you. We do not advise using bleach if you are surrounded by a body of water or other environment that could be affected.

Sunbrella should only be allowed to air dry.

Use of bleach and/or advanced age of the fabric application may impact the deterioration of the sewing thread and othernon-Sunbrella components.
