How to Clean and Maintain Your Composite Deck

Routine Cleaning

To maintain the beauty and performance of your composite deck, regular cleaning is essential. For routine care, sweep your deck with a soft-bristle broom to remove dirt, leaves, and debris. This should be done at least once a week or more frequently during peak usage and when debris is noticeable. Regular sweeping prevents the buildup of moisture-trapping materials, which can cause mold or mildew growth on your composite deck.

It’s also a good idea to wash down your composite deck with water from a hose to further remove dirt and grime. Be sure to use a gentle spray setting to avoid causing damage to the decking material. You can perform this light cleaning monthly or whenever you notice visible dirt on the deck surface.

Deep Cleaning

While composite decking is designed to be low-maintenance, deep cleaning is recommended at least twice a year, typically in spring and fall. To effectively clean your composite deck:

1. Fill a bucket with warm water and a gentle, non-abrasive composite deck cleaner, such as those recommended by your decking manufacturer. Follow the manufacturer’s instructions for mixing and dilution ratios.

2. Use a soft cloth or sponge to gently scrub the deck surface, starting from one end and working your way to the other. Avoid using a wire brush or any abrasive material, as it can damage the deck surface.

3. Pay special attention to high-traffic areas and spots where dirt or stains are more pronounced. Some stains, such as oil or grease spills, should be cleaned immediately to prevent permanent damage to the deck surface.

4. After scrubbing the entire deck, rinse it thoroughly with clean water from a hose to remove any remaining cleaning solution.

5. Allow the deck to dry completely before placing furniture or other items back on the surface.

Removing Mold and Mildew

Mold and mildew can occasionally develop on composite decking, especially in damp and shady areas. To remove mold and mildew, follow these steps:

1. Choose a mold and mildew cleaner specifically formulated for composite decks, available at most home improvement and hardware stores.

2. Read the manufacturer’s instructions carefully and follow their guidelines for application and safety precautions.

3. Apply the cleaner directly to the affected areas and let it sit for the recommended time (usually 10-15 minutes).

4. Use a soft-bristle brush to scrub the mold and mildew away, taking care not to damage the deck surface.

5. Rinse the deck thoroughly with clean water to remove the mold, mildew, and cleaning solution.

6. Allow the deck to dry completely. To prevent the return of mold and mildew, ensure proper ventilation and drainage around your composite deck. Keep the area clear of debris and minimize prolonged moisture exposure.

Preventing Scratches and Damage

Composite decking is designed to be durable and resistant to everyday wear and tear. However, it’s essential to take steps to protect your deck from scratches, dents, and other damage. To safeguard your composite deck:

1. Use protective furniture pads or glides on the legs of chairs, tables, and other deck furniture to prevent scratches from moving items.

2. Avoid dragging heavy objects across your deck surface. If you need to move a large item, use a dolly or lift it with the help of another person.

3. Place a grill mat under your outdoor grill to catch grease and prevent spills from staining the deck surface.

4. Trim back nearby trees and bushes to prevent branches from scratching or damaging your deck.

5. Be cautious with metal shovels when removing snow from your composite deck. Instead, use a plastic shovel or a broom to prevent damaging the surface.

Seasonal Maintenance

To keep your composite deck in peak condition, perform seasonal maintenance checks at the start and end of the outdoor season. This can include:

1. Inspecting your deck for signs of damage, wear, or mold and mildew growth. Address any issues promptly to prevent further complications.

2. Tightening or replacing loose or damaged fasteners and deck hardware.

3. Cleaning and sealing any cuts or exposed ends where the composite material has been cut or modified. This will help prevent the infiltration of water and reduce the risk of decay or damage.

4. Checking for proper drainage around your deck, ensuring water is directed away from the deck surface and foundation.

By following these essential cleaning and maintenance steps, you’ll ensure your composite deck remains an attractive, functional, and enjoyable outdoor living space for many years to come.
