How to Clean Composite Decking

Simple Tips to Maintain Your Composite Deck

Composite decking offers the appeal of wood without the high maintenance. It’s durable and looks great, but it does need regular care. Cleaning composite decking is easy when you know how. With the right tools and a bit of effort, you can keep your composite deck in top condition.

Why Regular Cleaning Is Essential for Composite Decks

Composite decking is made from synthetic materials, making it resistant to rot and warping. However, it still collects dirt. Regular cleaning keeps your deck looking good and prevents mold and mildew.

• Weather Effects: Rain, wind, and sun can deposit dust, pollen, and mildew on your deck.
• Organic Debris: Leaves, bird droppings, and food spills can cause stains and attract pests.
• Mold and Mildew: Shaded, damp spots can develop these unsightly growths.

Even though composite decks require less upkeep than wood, regular cleaning is still necessary.

Tools and Supplies for Deck Cleaning

Before you start cleaning, gather these tools and supplies:

• Broom: To sweep away loose dirt and leaves.
• Bucket: To mix your cleaning solution.
• Mild Dish Soap: A gentle and effective cleaner.
• Soft-Bristled Brush: To prevent scratches while scrubbing.
• Water Hose: For rinsing the deck.
• Composite Deck Cleaner: For a deeper clean.
• Vinegar: For natural cleaning solutions.
• Leaf Blower (optional): For quick debris removal.
• Plastic Shovel (for winter care): To avoid scratching the deck.

Step-by-Step Guide to Clean Your Composite Deck

Step 1: Prepare Your Deck

Sweep your deck with a broom or leaf blower to remove loose dirt and debris. Move furniture to clean all areas.

Step 2: Rinse the Deck

Use a garden hose to rinse off loose grime. If you use a pressure washer, use a fan tip nozzle and follow the manufacturer's PSI guidelines to avoid damage.

Step 3: Apply Cleaner and Scrub

Mix warm water with mild dish soap or use a composite deck cleaner. Follow the cleaner’s instructions. There are also eco-friendly green cleaners available.

Step 4: Scrub Thoroughly

Use a soft-bristled brush to scrub your deck, following the grain of the boards. Don't forget to scrub the railings, corners, and gaps between the boards.

Step 5: Rinse Everything Off

Rinse the deck thoroughly with a garden hose to remove all soap residue. This prevents a film from forming on your decking.

Handling Common Composite Deck Cleaning Issues

Even with regular maintenance, composite decks can get stubborn stains and discoloration. Here are some tips to handle common problems:

• Stubborn Stains: Clean spills immediately. For food, oil, or grease, use a mix of dish soap and warm water.
• Mold and Mildew: Mix one part vinegar with four parts water, scrub the affected areas, and rinse thoroughly.
• Pollen and Sap: Use mild dish soap and a gentle scrub. Avoid harsh chemicals.
• Winter Care: Remove snow and ice promptly. Use a plastic shovel with rounded edges to avoid scratching the deck.

Avoid Harsh Chemicals: Bleach, ammonia, and other harsh chemicals can damage your deck and fade its color. Use mild cleaners and natural solutions instead.

Preventative Care for Your Composite Deck

To keep your composite deck looking its best, follow these simple preventative steps:

• Minimize Abrasion: Lift furniture instead of dragging it to avoid scratches.
• Reduce Dirt Accumulation: Place mats at entry points to reduce dirt tracked onto the deck.
• Regular Sweeping: Sweep your deck regularly to prevent dirt and debris buildup.
• Gentle Rinse: A gentle hose down with a spray nozzle can keep your deck looking fresh.

The Importance of Regular Maintenance

Regular cleaning is vital for keeping your composite decking inviting, vibrant, and durable. Proper care extends the life of your deck and keeps it looking beautiful.
