Cleaning and maintaining Wood Plastic Composite (WPC) products is relatively easy compared to natural wood, as WPC is resistant to rot, insects, and moisture. However, regular care is necessary to keep the surface looking fresh and to ensure its longevity. Here are steps and tips for cleaning and maintaining WPC products:

  1. Routine Cleaning

 

Regular cleaning helps to remove dirt, debris, and organic material that may accumulate on the surface, especially in outdoor settings. Routine cleaning can prevent mold, mildew, and staining.

 

# Steps:

– Step 1: Sweep the Surface

– Use a soft-bristle broom or brush to sweep away loose dirt, leaves, and other debris.

– Pay special attention to gaps between the boards, where debris can accumulate.

 

– Step 2: Wash with Soap and Water

– Mix a mild detergent or dish soap with warm water in a bucket.

– Use a soft sponge or soft-bristle brush to scrub the surface gently.

– Avoid using stiff or wire brushes that could scratch the WPC surface.

 

– Step 3: Rinse Thoroughly

– Use a garden hose or a bucket of water to rinse off the soap and loosened dirt.

– Make sure to rinse thoroughly to avoid soap residue that could attract dirt.

 

# Frequency:

– Perform routine cleaning every 1-2 months, depending on the environment (more frequently in high-traffic areas or regions with heavy rain or dust).

  1. Removing Stains

 

WPC materials can occasionally get stained from spills such as food, grease, oil, or even plant matter. It’s important to tackle stains as soon as possible to prevent them from setting in.

 

# Steps:

– Step 1: Spot Clean Immediately

– Wipe up the spill as soon as it happens with a damp cloth.

 

– Step 2: Use a Composite Cleaner

– For tougher stains like grease or oil, use a composite deck cleaner or a mild household degreaser.

– Apply the cleaner to the stained area and let it sit for a few minutes.

 

– Step 3: Scrub Gently

– Use a soft brush or sponge to scrub the stained area. Avoid using harsh scrubbers or steel wool.

 

– Step 4: Rinse

– Rinse the area thoroughly with clean water to remove the cleaner and any residual stain.

 

# Common Stain Types and Cleaners:

– Grease or Oil Stains: Use a degreaser or a mild composite cleaner.

– Food Stains: Warm water and mild soap should work, but composite cleaners can be used for tougher stains.

– Tannin Stains (from leaves or plants): Use a specialized deck cleaner or oxalic acid-based cleaner.

  1. Dealing with Mold and Mildew

 

While WPC is moisture-resistant, organic matter (such as dirt, leaves, or pollen) can promote the growth of mold or mildew, especially in shaded or damp areas. Address mold or mildew as soon as it appears.

 

# Steps:

– Step 1: Clean with Soap and Water

– Start by cleaning the affected area with soapy water and a soft brush to remove surface dirt and mold spores.

 

– Step 2: Use a Mold and Mildew Cleaner

– For stubborn mold or mildew, use a mildew remover or a mixture of white vinegar and water.

– Apply the cleaner and let it sit for 10-15 minutes to break down the mold.

 

– Step 3: Scrub and Rinse

– Gently scrub the area with a soft-bristle brush and rinse thoroughly with water.

 

– Step 4: Dry the Surface

– Allow the surface to air dry completely. Ensure that no water accumulates on or under the boards, as this can promote future mold growth.

 

# Preventive Measures:

– Keep the surface clear of organic debris (like leaves and dirt) that can trap moisture and encourage mold growth.

– Ensure proper airflow and drainage to prevent water from accumulating in certain areas, especially beneath the deck or in hidden spaces.

  1. Winter Care

 

In cold climates, snow and ice can accumulate on WPC decks or outdoor furniture. Proper winter care is important to maintain the surface and prevent damage.

 

# Steps:

– Step 1: Snow Removal

– Use a plastic snow shovel to clear snow. Avoid using metal shovels, as they can scratch the surface.

 

– Step 2: De-Icing

– To prevent ice buildup, use a calcium chloride-based de-icer (not rock salt, as it can damage WPC surfaces).

– Spread the de-icer evenly across the surface, and be cautious not to overuse it.

 

– Step 3: Clean After Thawing

– Once the ice and snow have melted, clean the surface with soapy water to remove any residue from the de-icing salts.

  1. Avoiding Damage

 

To keep WPC products in good condition, it’s important to take steps to avoid scratches, dents, and other forms of damage.

 

# Precautions:

– Heavy Furniture: Use protective pads under the legs of heavy outdoor furniture to prevent indentations or scratches.

– Avoid Dragging Items: Do not drag heavy objects across the surface, as this can cause scratches. Lift and move them instead.

– Use Mats: In high-traffic areas, consider using breathable outdoor mats or rugs to protect the surface. Make sure mats allow for air circulation to avoid moisture buildup.

  1. General Maintenance

 

Perform regular inspections to maintain the integrity and appearance of WPC products.

 

# Tasks:

– Check for Loose Fasteners: Regularly inspect fasteners, screws, or clips to ensure that the WPC boards are secure. Tighten or replace any loose or damaged fasteners.

– Monitor for Fading: Over time, WPC materials may fade slightly due to UV exposure. Consider using a UV-protectant finish if fading becomes noticeable.

– Inspect for Cracks or Warping: Check for any cracks, warping, or other damage, especially after extreme weather. Replace damaged boards if necessary.

  1. Pressure Washing (With Caution)

 

If necessary, you can use a pressure washer to clean WPC products, but it must be done carefully to avoid damage.

 

# Steps:

– Step 1: Set to Low Pressure

– Use a pressure washer with a maximum of 1500 PSI.

– Keep the nozzle at least 12 inches away from the surface to prevent gouging or scratching.

 

– Step 2: Test a Small Area

– Test the pressure washer on a small, inconspicuous area first to ensure it does not damage the WPC surface.

 

– Step 3: Move Gently

– Work in the direction of the grain (if there is one) and move the spray evenly across the surface. Avoid focusing on one spot for too long.

  1. Long-Term Care

 

To extend the life of WPC products, it’s important to take a few long-term care steps.

 

# Tips:

– Protect from Direct Sunlight: Consider installing shading structures (like pergolas or umbrellas) in areas exposed to direct sunlight to reduce fading.

– Avoid Harsh Chemicals: Do not use harsh chemicals such as bleach, acetone, or solvents, as they can damage or discolor the WPC material.

– Reapply Sealant (Optional): Some WPC products can benefit from the application of a UV-protective sealant every few years, depending on the manufacturer’s recommendations.
