How can you cleaning the WPC decking ?

Cleaning outdoor composite decking is straightforward, but regular maintenance can help keep it looking great and extend its lifespan. 

Here's a detailed guide to properly clean your outdoor composite deck:

 1. Regular Sweeping

Outdoor composite decking is often exposed to dust, leaves, and small debris. Regularly sweep the deck with a broom or use a leaf blower, especially during fall or windy seasons. This prevents debris from accumulating in the gaps, which could affect drainage and potentially damage the decking over time.

2.Rinse with Water

For light dirt and grime, simply use a garden hose to rinse off the surface. A gentle stream of water will easily wash away loose dirt, dust, or any other surface contaminants. Make sure to rinse in the direction of the deck’s grooves to prevent water from pooling in between the boards.

3. Dealing with Stubborn Stains

Though composite decking is generally resistant to stains, more persistent spots such as mud, grease, or spilled beverages may require more attention. Use a soft-bristle brush along with warm water and a mild soap or detergent to scrub these areas gently. Avoid using metal brushes or harsh scrubbers that could scratch the deck’s surface. After scrubbing, rinse thoroughly with clean water to remove all traces of soap or cleaner.

4. Avoid High-Pressure Washers

While pressure washing can be efficient, it's not always recommended for composite decking as excessive pressure may damage the surface, causing it to roughen or crack. If you must use a pressure washer, set it to a low-pressure setting and keep the nozzle at a safe distance from the deck (at least 12 inches), ensuring you don’t damage the material.

 5. Removing Mold and Mildew

In humid climates or shady areas, mold or mildew can develop on the deck. If you spot any, use a mold and mildew cleaner or a diluted bleach solution (1 part bleach to 3 parts water). Spray the solution on the affected area and let it sit for about 10-15 minutes, then gently scrub with a soft brush. Afterward, rinse thoroughly with water to remove all cleaning residues. Regularly checking for mold growth can prevent it from spreading and help maintain the deck's cleanliness.

6. Cleaning Oil and Grease

For oil or grease stains (such as from outdoor cooking or grilling), apply a mild dish soap and warm water to the stain. Let the solution sit for a few minutes before scrubbing with a soft brush. If the grease is stubborn, use a degreasing product specifically formulated for composite decks. Always make sure to rinse away the cleaning solution completely after treating the area.

7. Regular Inspection and Maintenance

In addition to cleaning, periodically inspect the deck for any signs of damage, such as warping or loose boards, especially in areas that experience heavy foot traffic or near walls and edges. Address small issues promptly to prevent more significant problems in the future. This is especially important in regions with extreme weather conditions, where decking is exposed to prolonged sun or moisture.

8. Choose Appropriate Cleaning Tools

When selecting cleaning tools, avoid abrasive materials like metal brushes or hard sponges that could scratch or wear down the surface of the composite decking. Instead, opt for soft-bristle brushes, plastic scrubbers, or soft cloths. As for cleaning agents, avoid harsh chemicals or strong acids/alkalis, which could harm the deck’s surface. Stick to mild cleaners specifically formulated for composite materials.

Conclusion

By following these simple but effective cleaning steps, you can maintain the beauty and functionality of your composite decking for years. Regular sweeping, rinsing, and occasional deep cleaning for tough stains and mold will keep the deck in top shape. When cleaning, always use the right tools and products to avoid damaging the surface, and be mindful of pressure washing to preserve the deck’s integrity.
