The life of your parasol canopy can be increased by both using a protective cover when not in use, and occasional maintenance. It is important that the cover is completely dry before using a Bambrella® protective cover. Fabric life can be extended by simply washing down the cover periodically with warm soapy water using a sponge or soft brush, to remove any dirt or other substances on which mildew may form. Do NOT tumble dry, air dry instead. For Sunbrella fabrics, most stains can be cleaned up with a mild soap and water solution. Solution-Dyed fabrics 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 umbrella. Simply brush off any loose dirt, etc., clean with warm water (no more than 100 degree F) and a mild natural soap. Rinse thoroughly to remove soap. When using liquid detergent, it may be necessary to re-apply a water repellent treatment, such as 303 Hi Tech Fabric Guard. 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 Solution-Dyed fabrics are 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 Stain Cleaning Chart for more specific cleaning instructions. Before storing at the end of the season, make sure that the fabric is free from dirt and moisture to prevent surface deterioration.
