Ultraviolet Protection Factor (UPF)
Fabric should be cared & cleaned regularly before substances such as dirt, roof particles, etc., accumulated on and become embedded in the fabric. The fabric can be cleaned without being removed from the installation. Simply brush off any loose dirt, roof particles, etc.; hose down and clean with a mild solution of natural soap in lukewarm water(no more than 100 degree F.). Rinse thoroughly to remove soap. DO NOT USE DETERGENTS. Air dry is fine.Please care & clean the fabrics regulary before storing, and covering with a protective umbrella cover is a wise way for longer life of your canopy. Please close your garden umbrellas or gazebos in strong windy or stormy conditions.
TEXTILE UV PROTECTION
Textiles are intrinsically suited for use as UV protection, as they are able to offer particularly good protection against intense radiation from the sun if suitable materials and constructions are used. UV protection factors (UPF) far above those of the strongest sunscreens (sunblocks) can be achieved.It is not possible to determine how much UV radiation a textile allows to penetrate the skin simply from looking at and feeling the textile and thereby give a UV protection factor comparable to those used for cosmetic sun screens.
