cleaning tips for composite decking

Julian Mossanen |

Composite and PVC decking have gained immense popularity among homeowners for their durability and low-maintenance nature. These materials provide an excellent option for outdoor spaces, but like any other surface, they require regular upkeep to preserve their beauty and ensure their longevity. In this blog, we will provide you with essential tips on how to clean and care for your composite decking, enabling you to enjoy a pristine outdoor space for years to come.

Importance of Regular Maintenance for Composite and PVC Decking

Maintaining your composite and plastic decking is crucial for several reasons. Firstly, regular maintenance ensures the longevity of your deck, allowing you to enjoy it for many years. Secondly, it prevents discoloration, mold growth, and other damages that may arise from neglect. By following the cleaning and care tips provided in this blog, you can maintain the beauty and structural integrity of your deck.

Cleaning Tips for Composite and PVC Decking

Sweeping or Blowing Away DebrisStart by removing dirt, leaves, and other debris from your deck using a broom or a blower. This step prevents the buildup of materials that could cause staining or other damage.

Pressure Washing: If your deck has stubborn stains you can use a pressure washer. We recommend power washing in the spring and fall or as required. Rice Hulls are very hard and power washing will not harm the board. Power wash using soap detergent and a hose fan spread of 6” or more. Maintain a safe distance from the deck while pressure washing.

Using a Suitable Cleaning SolutionInvest in a high-quality composite deck board cleaner that is formulated specifically for these materials. Ensure that the cleaner is safe for use on your deck by checking the label. Follow the manufacturer's instructions for the correct application and optimal results.

Mild Soap and Water: For more stubborn stains or spills, a solution of mild soap and water can be highly effective. Mix a gentle, non-abrasive soap with warm water and use a soft-bristle brush or sponge to scrub the affected areas. Rinse thoroughly afterward to avoid any soap residue.

Specialized Cleaners: There are specialized composite deck cleaners available in the market that are designed to tackle specific stains like mold, mildew, or grease. Follow the manufacturer's instructions for the product, and always test in a small, inconspicuous area before applying to the entire deck.

Caring for Composite and PVC Decking

Avoiding the Use of Harsh ChemicalsAlthough composite or plastic decking is designed to resist harsh chemicals, it is best to avoid using them whenever possible. This includes bleach or other cleaning agents that may cause damage. Stick to mild cleaning solutions that are specifically formulated for your deck.

Furniture Pads: If you have furniture on your deck, place protective pads underneath the legs to prevent scratches and abrasions on the decking surface. Be cautious when moving heavy furniture or other objects on the deck. Lift items rather than dragging them to avoid scratching the surface.

Regular CleaningSchedule regular cleaning sessions for your composite or PVC decking board to prevent the buildup of dirt and rust . By sweeping or blowing away debris and conducting periodic deep cleanings, you can maintain the pristine appearance of your deck and extend its lifespan.

Addressing Cracks and CrevicesPay attention to any cracks or crevices that may appear on your decking. Promptly address these issues by filling them with an appropriate deck filler or contacting a professional for repairs. This proactive approach can prevent further damage and ensure the structural integrity of your deck.


Maintaining the beauty and performance of your composite or PVC decking is essential for maximizing its lifespan and enjoying a stunning outdoor space. By following the cleaning and care tips outlined in this blog post, you can easily keep your deck in top condition. Regular cleaning, avoiding harsh chemicals, keeping the deck dry, and addressing any areas of concern are key elements to ensure the long-lasting beauty and durability of your composite or PVC decking. With proper care, you can create a space that you and your loved ones can enjoy for years to come.
