Tips on Cleaning Your Composite Deck

Tip 1: Regular Sweeping to Remove Debris

Regular sweeping is an essential step in maintaining a clean composite deck. Leaves, twigs, and other debris can accumulate on your deck, leading to discoloration and potential damage. Use a broom or a stiff brush to sweep away the debris. Start from one end of the deck and work your way to the other end, ensuring that all areas are thoroughly cleared.

For better efficiency, consider using a leaf blower to remove loose debris quickly. This will save you time and effort, allowing you to focus on other essential tasks. Make sure to pay extra attention to corners, gaps between the boards, and any hard-to-reach areas where debris tends to collect.

Tip 2: Gentle Power Washing for Deep Cleaning

While regular sweeping removes most surface dirt, a deep clean is necessary to eliminate stubborn stains, mold, and mildew. Power washing is an effective method for deep cleaning your composite deck.

Before you start power washing, make sure to read the manufacturer's guidelines for your specific composite deck material. Adjust the water pressure to a gentle setting to avoid damaging the surface. Using a wide-angle spray nozzle will help distribute the water evenly and prevent streaking.

Begin power washing from one end of the deck, moving slowly and methodically to ensure thorough cleaning. Pay attention to areas with visible stains or discoloration, such as around barbecue grills or seating areas. Take caution not to linger in one spot for too long, as this can cause damage to the deck.

After power washing, allow the deck to dry completely before moving on to the next step. This will prevent moisture from getting trapped and potentially causing problems in the future.

Tip 3: Using Mild Cleaning Solutions for Stubborn Stains

For stubborn stains that cannot be removed through regular sweeping or power washing alone, consider using a mild cleaning solution. Avoid harsh chemicals and abrasive cleaners, as they can damage the composite material. Instead, opt for gentle, environmentally-friendly solutions.

A mixture of warm water and mild dish soap is often sufficient for most stains. Apply the solution to the affected area and scrub gently with a soft-bristle brush or sponge. Rinse thoroughly with clean water to remove any soap residue. For more stubborn stains, you can also try using a specialized composite deck cleaner recommended by the manufacturer.


Cleaning your composite deck doesn't have to be a daunting task. By following these 3 easy tips - regular sweeping, gentle power washing, and using mild cleaning solutions - you can keep your deck looking fresh and beautiful year-round. Remember to always follow the manufacturer's guidelines for your specific composite deck to ensure proper maintenance and avoid any potential damage.
