  • Washing a Sunbrella boat cover.

    My local shop said to go to the laundrymat & wash it in one of the big tubs & to use soap, not detergent. I did that & it ain't all that clean. They did have one size bigger washer that I will use next time because as it was washing I could see that it needed more room to tumble. It's a lot cleaner that it was but it still ain't all that clean. Some spots are perfect others are somewhat soiled. Anybody have any tips besides using the largest washer & washing it more often than every two years? Thanks in advance.

    You may have to spot clean with a solution of water and bleach.Start with a 10 to 1 dilution and avoid any threads if possible.Start with the canvas being saturated with water and then spray the solution on the area.Leave it for about 5 minutes and then use a soft brush on it and rinse thoroughly.I have used stronger solutions of bleach and water when needed.If the piece is made of Sunbrella you wont stain or discolor it.You can also try pressure washing it where the stain is.Most of the time there is a dark stain that wont come out ,it is some form of mildew.If you are afraid to use the bleach you can try straight white vinegar.Saturate the stain and roll it up and let it sit overnight so it will remain wet and then try to scrub it out the next day.NEVER put it in a dryer.It is best to put it back on the boat while wet and then let it dry there to keep it from shrinking at all.Post back your results so we will all know what worked.You will also have to waterproof it when you are done.Charlie

      From the Sunbrella Website:
      Awning/Marine One of the best ways to keep Sunbrella brand fabrics looking good and to delay the need for deep or vigorous cleanings is to hose fabrics off on a monthly basis with clear water. This practice will help prevent dirt from becoming deeply imbedded in the fabric and eliminate the need for more frequent vigorous cleanings. 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 a boat 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 soap i.e. Ivory Snow, Dreft or Woolite. Never detergent. Water should be cold to lukewarm. Never more than 100 degrees. Air dry only. Never apply heat to Sunbrella fabrics. If you are cleaning Sunbrella while still on an awning frame or a boat, follow these simple steps:Brush off loose dirt. Hose down. Prepare a cleaning mixture of water and mild soap (no detergents). Use a soft bristle brush to clean. Allow soap to soak in. Rinse thoroughly. Air dry. 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 (see our Stain Chart for specific recommendations).Prepare a special cleaning mixture:Four ounces (half cup) of chlorine bleach. Two ounces (one-fourth cup) of mild soap. One gallon of water. Clean with soft bristle brush. Allow mixture to soak for up to 20 minutes. Rinse thoroughly. Air dry. Repeat if necessary. 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.If an awning or boat cover is suitable in size for a washing machine, these steps should be followed:Use only mild soaps. No detergent. Wash and rinse in cold water. Air dry. Never put Sunbrella fabrics in your dryer. 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 High Tech Fabric Guard™ as the preferred re-treatment product for Sunbrella fabrics. Fabrics should be retreated after thorough cleaning or after five years of use. Check with your local Sunbrella dealer or distributor for more information.Applying 303 High Tech Fabric Guard™ 303 should be applied to Sunbrella fabrics after each thorough cleaning, which typically removes the original fluorocarbon finish and reduces the fabric's water repellency. After cleaning the fabric, allow it to air dry completely and then apply 303 in a thin, even coat. After allowing the first coat of 303 to air dry, 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 lightweight fabric. Always apply 303 to clean fabric.Professional Awning Cleaners You may have access to professional cleaning firms that service awnings. 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 retreatment requirements.
