Weatherbest decking is one of the most popular brands of composite deck material on the market. To clean your Weatherbest decking, follow the methods suggested by Louisiana-Pacific Corporation, who manufacturers the product.
Rinse your deck every week with a garden hose so dust, pollen and other airborne pollutants don't accumulate.
Scrape any accumulated debris from between the deck planks. Use a plastic scraper and take care not to gouge the planks.
Wash your Weatherbest decking with a commercial deck wash that is rated for composite decking. Mix the suggested amount of solution (according to the manufacturer) with water and apply it to the deck with a mop. Allow the solution to soak for a half-hour, then rinse it off with a garden hose.
Remove grease stains by applying a household degreaser, such as a citrus-based orange cleaner. Allow the solution to stand for 15 minutes, then rinse.
Clean ground-in dirt with a pressure washer. Use a cleaning solution that is approved for both composite decking and pressure cleaners.
