Before beginning the cleaning process for your TimberTech deck, it is important to properly prepare the area by clearing the deck and gathering the necessary supplies. Here are the steps you should follow:

  4. Prepare the deck cleaner: Follow the manufacturer’s instructions to properly prepare the deck cleaner solution. This may involve diluting the cleaner with water and mixing it in a 5-gallon bucket.
  5. Gather other supplies: In addition to the deck cleaner, gather other supplies that you will need for the cleaning process. This may include a spray bottle, measuring cup, towels or sponges, and a deck brush with appropriate bristles.

Step-by-Step Cleaning Process

When it comes to maintaining the cleanliness and longevity of your composite deck, following a step-by-step cleaning process is crucial. By working in small sections and using the proper composite deck cleaner and brush, you can effectively remove dirt, grime, and stains. Here is a detailed guide to help you achieve a pristine and well-maintained deck:

Step 1: Saturate the Area

Start by saturating a small section of your deck with a diluted composite deck cleaner. Follow the manufacturer’s instructions for the appropriate ratio of cleaner to water. This will help loosen the dirt and prepare the surface for scrubbing.

Step 2: Scrub with Downward Pressure

Using a brush with appropriate bristles, scrub the saturated section of your deck with downward pressure. This will help dislodge any stubborn stains or dirt particles. Make sure to use a brush that is recommended for use on composite decking to prevent damage.

Step 3: Rinse Thoroughly

After scrubbing, thoroughly rinse the section with clean water. Use a hose or a pressure washer set at a low setting to remove any remaining cleaner and debris. It’s important to rinse off all the cleaning solution to prevent residue buildup.

Step 4: Remove Standing Water

If there is any standing water left on the deck after rinsing, use towels or a sponge mop to remove it. Standing water can lead to staining or damage if left unattended. Ensure that the deck surface is completely dry before moving on to the next section.

Repeat this step-by-step process for each section of your composite deck until the entire surface is clean. Remember to always follow the manufacturer’s guidelines for proper cleaning techniques and products to ensure the best results.

Choosing the Right Cleaner for Your Composite Deck

When it comes to cleaning your composite deck, using the right cleaner is essential to maintain its appearance and longevity. While there are various cleaning options available, it’s important to choose a product that is specifically designed for your deck material. In the case of TimberTech composite and PVC decking, we recommend using TimberTech DeckCleaner™ for optimal results.

It is specially designed to penetrate deep into the decking material, providing a thorough and gentle clean.

If you prefer to use an alternative cleaning solution, such as mild soap, it’s important to check with the manufacturer to ensure its compatibility with your specific deck. Different composite decking brands may have different cleaning recommendations, and using the wrong cleaner can potentially damage the surface. It’s always better to be safe than sorry when it comes to the care of your composite deck.

Cleaning Common Deck Issues

When it comes to maintaining the beauty and durability of your composite deck, it’s important to address common issues that can arise over time. By following the right cleaning methods and using suitable products, you can effectively tackle stains, mold, mildew, oil and grease, dirt and debris, hard water stains, and tannins.


Stains on your deck can come from various sources, such as food and drink spills, pet messes, or accidental spills of oil or grease. For minor stains, wipe them away with a clean cloth or sponge. For tougher stains, you may need to use a cleaning agent specifically designed for composite decking, applying it according to the manufacturer’s instructions.

Snow and Ice Removal

In winter, it’s important to remove snow and ice from your composite deck to prevent damage. Avoid using metal shovels or sharp objects that could scratch the surface. Instead, use a plastic shovel or a broom with soft bristles. Always be gentle when clearing snow and ice, taking care not to damage the deck boards.

Mold and Mildew

Mold and mildew can grow on your deck, especially in areas with high humidity or excessive moisture. To combat this issue, use a composite deck cleaner that is specifically formulated to remove mold and mildew. Scrub the affected areas with a brush and rinse thoroughly with clean water to ensure complete removal.

Oil and Grease

If you notice oil or grease stains on your deck, it’s essential to address them promptly. Use a suitable composite deck cleaner or a mild soap and water solution to clean the affected area. Scrub gently with a brush to lift the stains, then rinse thoroughly. Quick action can prevent the stains from setting in and becoming more difficult to remove.

Dirt and Debris

Regularly removing dirt and debris from your deck will help maintain its appearance and prevent scratches. Sweep the deck with a broom or use a leaf blower to clear away loose dirt and debris. Pay attention to corners and edges where dirt tends to accumulate. For stubborn dirt, you can use a composite deck cleaner and a brush to scrub the surface before rinsing.

Hard Water Stains

If you have hard water in your area, you may notice mineral deposits on your deck. These hard water stains can be difficult to remove with regular cleaning methods. Consider using a specialized cleaner designed to tackle hard water stains. Follow the product instructions carefully to ensure effective removal without damaging your deck’s surface.


Over time, certain types of wood used in composite decks may release tannins, which can cause discoloration. This discoloration often weathers away naturally with exposure to the elements. Regular cleaning and maintenance can help speed up this process. If tannin stains persist, consult the manufacturer for specific recommendations on how to address them.

Best Practices in Composite Deck Cleaning

When it comes to maintaining the beauty and longevity of your composite deck, following the best practices for cleaning is essential. By using the right cleaner and brush, you can effectively remove dirt, stains, and other impurities without causing damage to your deck. Here are some recommendations to ensure the best results:

  1. Choose a cleaner specifically designed for composite decking, such as TimberTech DeckCleaner™, which is formulated to work effectively and safely on TimberTech composite and PVC decking.
  2. Read and follow the manufacturer’s instructions for the cleaner you are using, as different products may have specific application and rinsing guidelines.
  3. Store your cleaning products and tools together for easy access, making it convenient to clean your deck on a regular basis.
  4. Clean your deck at least twice a year to prevent the buildup of dirt, stains, and other debris. Consider cleaning more frequently if your deck is exposed to extreme weather conditions or standing water.

Not only does following these best practices help maintain the appearance of your deck, but it also ensures that your cleaning efforts do not compromise the integrity of the materials.

Other Considerations for Deck Maintenance

When it comes to maintaining your deck, there are a few additional factors to consider for optimal care and preservation. One important consideration is to avoid using rubber-backed mats or certain non-porous items on your deck. These can trap moisture underneath and cause discoloration or even mold growth over time. Instead, opt for mats or rugs made specifically for outdoor use.

It is also crucial to be cautious with chemicals that come into contact with your deck. Certain products like sunscreen, insect repellent, or strong cleaning agents can stain or damage the surface of your deck. To prevent any mishaps, it’s best to wipe up spills or drips immediately and rinse the area thoroughly with water.

Protecting your deck from freezing weather is especially important. When the temperature drops, water can freeze and expand, leading to cracks or other damage. To prevent this, clear your deck of snow and ice using a plastic shovel or broom. Avoid using metal shovels, as they can scratch or gouge the deck surface.

Finally, regular maintenance and cleaning should not be overlooked. By removing debris, leaves, and dirt regularly, you can prevent them from scratching or staining the surface of your deck. Remember to follow the manufacturer’s guidelines for cleaning and maintenance to ensure the longevity and beauty of your deck for years to come.
