For extra cleaning power or to sanitize, mix 1/3 parts bleach with 2/3 parts water and apply the bleach mixture to the finish with a clean cloth. Allow the bleach solution to sit on the lumber for a few minutes; it will not affect the color of the lumber. Loosen any dirt or debris that may catch in the surface grooves of the lumber by scrubbing the bleach mixture with a soft-bristle brush. Rinse thoroughly, and air dry or wipe dry with a soft cloth.How to Clean Outdoor Fabric: Small stains can be removed with a mixture of mild dish soap and water. For tougher stains, mix 1 ounce of bleach with 30 ounces of water in a spray bottle. If possible, place a clean towel between the fabric and foam cushion to absorb any excess moisture. Set the nozzle to " fan" , then spray and wet out the entire side of the cover where the stain is. Wipe the entire cover with a clean cloth to remove any excess moisture, then spray the same area with clean water to rinse the bleach solution out of the fabric. Wipe the entire cover again with a clean cloth to remove any excess moisture, then allow the cover to air dry.
