Clean Sunbrella® Marine Canvas
One of the best ways to keep Sunbrella® fabrics looking good is to hose fabrics off on a monthly basis with clean 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 re-treatment depending on the age of the fabric.
If stubborn spills persist, you can use a diluted bleach/soap mixture for spot cleaning of mildew. For roof run-off or other similar spills a strong degreaser may be required. See our Cleaning Guide for specifc recommendations: sunbrella.com/cleaningguide
Heavy Cleaning For Stubborn Spills 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 spills:
- Prepare a solution of 1 cup of bleach and 1/4 cup mild soap per gallon of clean water.
- Allow mixture to soak into fabric for up to 15 minutes.
- Blot spill with a sponge or clean towel. (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.
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 rinsed thoroughly.
Retreating Sunbrella Fabrics
Sunbrella fabrics are engineered to provide long-term performance. After repeated thorough cleanings, or years of use and exposure, you may choose to refresh your fabrics with an appropriate retreating agent. We recommend 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 outlined.
- Allow Sunbrella to completely air dry.
- Apply retreatment in a wellventilated area following instructions on the container.
Professional Cleaners
You may have access to professional 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.
