How to Clean Composite Decking: A Simple Maintenance Guide

Composite decking is designed to be durable and low maintenance, making it an excellent choice for outdoor spaces such as gardens, terraces, and pool surrounds. Regular cleaning not only keeps the surface looking great but also helps maintain safety and long-term performance.

1. Regular Cleaning (Routine Care)

For everyday dirt, dust, and debris:

• Sweep the deck regularly to remove leaves and loose particles

• Rinse the surface with clean water

• Use warm water mixed with mild soap

• Scrub gently with a soft-bristle brush, following the board direction

Routine cleaning prevents dirt buildup and keeps the deck surface comfortable underfoot.

2. Removing Stains and Spills

For food, grease, or drink spills:

• Clean spills as soon as possible

• Apply mild detergent with warm water

• Gently scrub the stained area

• Rinse thoroughly to remove soap residue

Prompt cleaning helps avoid long-term staining, especially in high-use areas.

3. Mold and Mildew Prevention

While composite decking resists moisture, mold can grow on surface debris in damp or shaded areas:

• Remove standing water regularly

• Ensure proper drainage and airflow

• Clean shaded areas more frequently

Keeping the surface clean is the most effective way to prevent mold and mildew.

4. What to Avoid

To protect your composite decking:

• Avoid metal brushes or abrasive tools

• Do not use harsh chemicals or strong solvents

• Avoid high-pressure washers at close range

Always follow manufacturer recommendations for best results.

Conclusion

Cleaning composite decking is simple and requires minimal effort. With regular sweeping and occasional washing using mild soap and water, your deck can remain attractive, safe, and durable for years.
