Can You Power Wash Composite Decking?

TimberTech composite decking is very low maintenance. Our deck boards never have to be stained or deep cleaned - unlike hardwood decking products, they will last for decades with virtually no upkeep whatsoever.

However, we do recommend cleaning your deck occasionally to maintain its appearance. You can use a power washer to do this.
