What Are Outdoor Fabrics?

"Outdoor Fabrics" refer to woven textiles made from a wide variety of synthetic fibers, acrylic, polyester, olefin and various blends, including cotton.  These breathable fabrics are made "water repellent" by a chemical treatment process during manufacturing.  The treated fabric repels (beads) water, resists soiling, both water & oil based stains and impedes mildew formation.

With time and use the original repellency treatment is diminished, making periodic cleaning and re-treatment necessary.  The key to keeping your outdoor fabric looking great and extending its life is periodic cleaning followed by repellency re-treatment.

Save Money and Add Years To The Life Of Your Outdoor Fabric

Though the cleaning and re-treatment procedures in this pamphlet specifically apply to Sunbrella® and fabric "canvas" convertible topping, they also apply to most outdoor fabrics.

Waiting until your outdoor fabric is dirty, stained and/or leaking requires the use of harsh chemicals and physical cleaning methods which can diminish service life.

Simple Cleaning - It's Easy!

For Best Results

Cleaning: Use 303 Fabric / Vinyl Cleaner, 303 Aerospace Cleaner, 303 Convertible Top Cleaner or 303 Cleaner & Spot Remover or use a mild
natural soap (Ivory Soap) in lukewarm water (100°F max)
Use soft bristle brush, sponge or cloth to loosen any stubborn dirt.  Properly maintained fabric should require no more than light agitation.
Rinse THOROUGHLY to remove soil and cleaning agent.
Allow to air dry.

It's Easy With 303 High Tech Fabric Guard

Use only on new or newly cleaned, dry fabric. 
Spray on 303 High Tech Fabric Guard until damp. DO NOT SATURATE!
Allow fabric to dry thoroughly before using or storing. 
If time permits, two light coats are better than one medium coat. Allow to air dry thoroughly between coats.  

Coverage:
For Sunbrella, "canvas" convertible topping and similar weight fabrics, apply at the rate of 75-100 sq. ft. per 16 oz. trigger sprayer, 500-800 sq. ft. per gallon.  Expect greater coverage on lighter weight fabrics, less on heavier fabrics and carpeting.

Maintenance Tip: About once a month, use a water hose to gently spray off any dirt that has settled (outdoor Sunbrella).  This keeps dirt from settling in and extends the time between soap and water cleaning and retreating.

For Stubborn Stains: Soak the stained fabric for no more tahn 20 minutes in a solution of 1/2 cup (4 oz) of bleach and 2 oz 303 Fabric Cleaner or 303 Aerospace Cleaner or natural soap per gallon of warm water (100°F).

Tip For New Fabrics: During the fabrication process the factory finish can be worn causing the new fabric to "wet", most commonly at the seams.  To prevent or correct seam leaks, treat the seam with 303 High Tech Fabric Guard.

WARNING: Silicone "water repellent" products are not recommended.  These products are not compatible with the outdoor fabric's factory finish and actually promote staining.  Water "sealants" for wood and masonry also are not recommended.

Before using 303 High Tech Fabric Guard, read the label directions and warnings.
