Sunbrella® Fabric should be cleaned regularly before substances such as dirt, etc., are allowed to accumulate on and become embedded in the fabric. The fabric can be cleaned without being removed from the piece. Simply brush off any loose dirt, etc,; clean with water and a mild natural soap. When using liquid detergent, it may be necessary to reapply a water repellent treatment, such as 303 Hi Tech Fabric Guard or a similar product.

Sunbrella® is made from 100% acrylic fiber and is heat sensitive. When washing or cleaning, do not subject to excessive heat as the fabric will shrink. Do not steam press or dry in electric or gas dryers. Allow fabric to air dry.

In case Sunbrella® fabric is stored during the winter season, it should be cleaned, allowed to air dry and stored in a dry, well ventilated area.

For stubborn stains, please see the chart for more specific cleaning instructions.
