All exterior surfaces collect dirt, dust and contaminants. It is necessary to clean them periodically to keep them looking good. Green Plank wood composites are low-maintenance products, not no-maintenance products.
Periodic cleaning of Green Plank composite products are suggested, even if they appear clean, it is important to prevent the build-up of pollen/debris that can cause mold.
We recommend a basic cleaning with a composite deck cleaner or combination of soap (dishwashing detergent) , hot water and a soft bristle brush. After cleaning rinse thoroughly. If unsure about the product being used to clean/ remove stains from your deck, it is recommended that you test a small area in an inconspicuous place to determine if the product will cause any unwanted discoloration.
Hose off the entire deck with a garden hose and not with a pressure washer. The pressure washer will spray particles of soap on other surfaces, possibly causing staining. Using a garden hose is a better practice to gently rinse off homemade cleaner and get rid of all water spots.
