run-off or other similar stains (see our Stain Chart
for specific recommendations).
Heavy cleaning for stubborn stains and mil-
dew 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 mildew or other stub-
born stains:
• Eight ounces (1 cup) of chlorine bleach.
• Two ounces (¼ cup) of mild soap and/or detergent.
• One gallon of water.
• Clean with a soft bristle brush.
• Allow mixture to soak into fabric for up to 15
minutes.
• Rinse thoroughly until all soap residue is removed.
• Air dry.
• Repeat if necessary.
• Re-treatment of fabric for water and stain
resistance will be necessary.
Remember to protect the area around your Sun-
brella if using a bleach solution. Carpet or other
fabrics that are not Sunbrella may have an ad-
verse reaction to the bleach.
• Use mild soap and/or detergent.
• 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 fab-
rics 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. Fabrics should be re-
treated after thorough cleaning or after five years
of use.
*Synthetic fabric heat settings normally do not
exceed 150°F/66°C Applying 303 High Tech Fabric
Guard 303 should be applied to Sunbrella fabrics
after each thorough cleaning, which typically re-
moves 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 the
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.
• A 15-ounce bottle provides coverage of up to
50 square feet of fabric.)

Helpful Hints
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.
Sunbrella air dries very quickly. Machine drying is not
necessary.
If the fabric has some wrinkling, use an iron, if neces-
sary, but only on the synthetic* setting. As some irons
exceed the recommended 100°F/38°C temperature on
the synthetic setting, test a small inconspicuous area
before ironing entire piece.
*DO NOT use a steamer or iron set to steam setting.
*Use of bleach and/or advanced age of the fabric
application may impact the deterioration of the sewing
thread and other non-Sunbrella components.
*DO NOT dry clean Sunbrella
