When you use DEFY Composite Deck Cleaner, you can watch it work as it foams up and penetrates down into the pores of the wood, giving your composite deck a thorough cleaning. To use, simply mix a 3/4 cup of cleaner to each gallon of water. A gallon of solution will treat 100-200 sq. ft. This product works best when mixed with luke-warm water. Product can be applied with a mop, deck brush, or pump-up garden sprayer. If using a garden sprayer, pour solution through a mesh cheese-cloth to filter out any undissolved granules to prevent sprayer nozzle from clogging. Once solution is applied to the deck, allow it to set for 15-20 minutes, then scrub with a stiff-bristle brush and rinse completely. A pressure washer can be used instead of a scrub brush if desired, but remember to use the lowest pressure tip possible to avoid damaging the surface.
DEFY Composite Deck Cleaner is recommended for use on all vinyl and composite decks as well as vinyl and aluminum siding. A 2.25 lb. container of DEFY Composite Deck Cleaner makes 6 gallons of solution and will clean approximately 600-1,200 total square feet (or 100-200 square feet per gallon).
