Proper cleaning and maintenance of your deck can help prolong its lifespan and keep it looking great for years to come. The best way to clean and maintain a deck depends on the material it's made of. Here are some tips for cleaning and maintaining wood and composite decking: Wood decking: Wood decks should be cleaned and resealed every year or two to protect against moisture, rot, and insect damage. To clean a wood deck, use a pressure washer or scrub brush and a mild detergent solution. Avoid using bleach or harsh chemicals, as they can damage the wood. After cleaning, allow the deck to dry completely before resealing it with a waterproofing or deck stain product. Composite decking: Composite decks are low maintenance and typically only require periodic cleaning to remove dirt and debris. To clean a composite deck, use a soft-bristle brush and a mild detergent solution. Avoid using pressure washers or abrasive cleaners, as they can scratch the surface of the deck. Rinse the deck thoroughly with a hose after cleaning. In addition to regular cleaning, it's important to inspect your deck annually for signs of damage or wear and tear. Replace any damaged or rotting boards, and tighten any loose screws or nails. If you're unsure about how to properly clean and maintain your deck, consult with a professional deck builder or contractor for advice. If you want to learn more read our Decking Guide.
