Hollow Composite Decking

Understanding Hollow Composite Decking

Before diving into the cleaning process, it’s essential to understand what hollow composite decking is and why it’s a popular choice for outdoor decks. Hollow composite decking is made from a combination of recycled wood fibers and plastic polymers, creating a material that is both strong and resistant to various environmental factors. The hollow design of the decking boards not only reduces weight but also provides excellent drainage, preventing water from pooling and causing damage.

One of the key advantages of hollow composite decking is its low maintenance requirements compared to traditional wood decks. However, it still needs to be cleaned regularly to remove dirt, debris, mold, and mildew that can accumulate over time. By following the right cleaning methods, you can keep your deck looking its best and extend its lifespan.

Regular Maintenance Cleaning

The first step in keeping your hollow composite decking clean is to establish a regular maintenance cleaning routine. This simple practice can prevent dirt and stains from building up and make deeper cleaning tasks less frequent and easier to manage.

  • Sweeping or Blowing: Start by removing loose dirt, leaves, and debris from the deck surface using a broom or a leaf blower. This step is crucial as it prevents these particles from getting trapped and causing scratches or discoloration. Make sure to sweep or blow in the direction of the decking boards’ grooves to ensure thorough cleaning.
  • Hosing Down: After sweeping, use a garden hose to rinse the deck thoroughly. The high – pressure water can help remove any remaining dust and small particles. Pay special attention to the areas around furniture, planters, and corners where dirt tends to accumulate.

Removing Stains and Spots

Despite regular maintenance, stains can still occur on your hollow composite decking. Here are some common types of stains and how to remove them:

  • Food and Beverage Stains: For fresh food and beverage stains, gently blot the area with a clean cloth or paper towel to absorb as much of the liquid as possible. Then, mix a mild dish soap with warm water and use a soft – bristled brush to scrub the stain. Rinse the area thoroughly with water. For stubborn stains, you may need to repeat the process or use a specialized composite deck cleaner.
  • Oil and Grease Stains: Oil and grease stains can be more challenging to remove. Sprinkle baking soda or cornstarch on the stain and let it sit for a few hours to absorb the oil. Then, sweep away the powder and scrub the area with a degreaser or a mixture of dish soap and warm water. Rinse thoroughly.
  • Mold and Mildew: Mold and mildew thrive in damp and shaded areas. To remove them, mix one part bleach with three parts water in a spray bottle. Spray the solution onto the affected area and let it sit for 10 – 15 minutes. Scrub the area with a soft – bristled brush and rinse thoroughly with water. Be sure to wear gloves and eye protection when using bleach, and avoid using it on a sunny day as it can cause discoloration.

Deep Cleaning

Periodically, your hollow composite decking will require a more thorough deep – cleaning to remove ingrained dirt and restore its original appearance.

  • Using a Composite Deck Cleaner: There are many commercial composite deck cleaners available on the market. Choose a cleaner specifically formulated for composite decking and follow the manufacturer’s instructions carefully. Generally, you’ll need to dilute the cleaner with water, apply it to the deck surface using a pump sprayer, and let it sit for a specified period. Then, scrub the deck with a soft – bristled brush and rinse thoroughly.
  • Pressure Washing: Pressure washing can be an effective way to deep – clean your deck, but it must be done correctly to avoid damaging the decking. Use a pressure washer with a low – pressure setting (around 1500 – 2000 PSI) and a wide – angle spray tip. Keep the nozzle at least 12 inches away from the deck surface and move it in a slow, even motion. Avoid pressure washing in the same spot for too long, as this can cause the decking to splinter or fade.

Preventive Measures

In addition to regular cleaning, taking preventive measures can help keep your hollow composite decking in top condition.

  • Furniture Pads: Place furniture pads under the legs of your outdoor furniture to prevent scratches and dents on the deck surface. This is especially important for heavier items like tables and chairs.
  • Regular Inspections: Periodically inspect your deck for any signs of damage, such as cracks, loose boards, or discoloration. Address any issues promptly to prevent further damage.
  • Sealing (Optional): While hollow composite decking is generally resistant to moisture and stains, some homeowners choose to apply a sealant to enhance its protection. If you decide to seal your deck, make sure to use a product specifically designed for composite materials and follow the application instructions carefully.
