How to Clean Composite Decking

Composite decking has become increasingly popular due to its durability, low maintenance requirements, and aesthetic appeal. However, like any outdoor surface, it requires occasional cleaning to maintain its pristine condition. In this article, we’ll delve into the step-by-step process of effectively cleaning composite decking to ensure it stays beautiful and functional for years to come.

Why Clean Composite Decking?

Composite decking is often touted as a low-maintenance alternative to traditional wood decking. While it does require less upkeep than wood, it’s not completely maintenance-free. Over time, dirt, grime, mould, mildew, and other debris can accumulate on the surface, detracting from its appearance and potentially compromising its longevity. Take a look at this range of black composite decking.

Regular cleaning not only enhances the aesthetic appeal of your composite decking but also helps prevent mould and mildew growth, which can cause slippery surfaces and pose safety hazards. Additionally, removing debris and stains promptly can prevent them from becoming deeply embedded in the material, making cleaning more challenging down the line.

Preparing for Cleaning

Before diving into the cleaning process, it’s essential to gather the necessary supplies and prepare your deck accordingly. Here’s what you’ll need:

Broom or Leaf Blower: Start by sweeping or using a leaf blower to remove loose debris such as leaves, twigs, and dirt from the surface of the deck. This step will make the cleaning process more effective and prevent debris from getting in the way.

Mild Detergent or Composite Deck Cleaner: Choose a gentle detergent or a cleaner specifically formulated for composite decking. Avoid using harsh chemicals or abrasive cleaners, as they can damage the surface of the deck.

Soft Bristle Brush or Sponge Mop: Opt for a soft-bristled brush or a sponge mop to scrub the deck gently. Avoid using wire brushes or abrasive scrubbers, as they can scratch the surface of the decking material.

Bucket and Water Hose: Fill a bucket with warm water and add the detergent or composite deck cleaner according to the manufacturer’s instructions. Additionally, keep a water hose nearby for rinsing off the cleaning solution.

Safety Gear: While composite deck cleaners are generally safe to use, it’s a good idea to wear gloves and protective eyewear to prevent skin and eye irritation. If you’re using a pressure washer, follow the manufacturer’s instructions and wear appropriate safety gear, including ear protection.

Once you’ve gathered your supplies, it’s time to prepare your deck for cleaning. Here’s what you need to do:

Clear the Deck: Remove any furniture, planters, or other items from the deck to give yourself ample space to work. If possible, relocate them to another area of your outdoor space temporarily.

Protect Nearby Plants: If you have plants or landscaping near your deck, consider covering them with plastic sheeting or watering them thoroughly before cleaning to prevent any cleaning solution from dripping onto them and potentially causing damage.

Test the Cleaning Solution: Before applying the cleaning solution to the entire deck, it’s a good idea to test it on a small, inconspicuous area to ensure it doesn’t cause any adverse reactions or discoloration. Wait for the test spot to dry before proceeding.

Cleaning Composite Decking

Now that you’ve prepared your deck and gathered all the necessary supplies, it’s time to roll up your sleeves and get to cleaning. Follow these step-by-step instructions to effectively clean your composite decking:

Apply the Cleaning Solution: Start by applying the detergent or composite deck cleaner to the surface of the deck. You can do this by pouring the solution directly onto the deck or using a pump sprayer for more even coverage. Be sure to follow the manufacturer’s instructions regarding the dilution ratio and application method.

Scrub the Deck: Using a soft-bristled brush or sponge mop, scrub the deck surface in small sections, working in the direction of the grain. Pay extra attention to areas with stubborn stains or heavy buildup of dirt and grime. Take your time and apply gentle pressure to avoid damaging the decking material.

Let the Solution Sit: After scrubbing, allow the cleaning solution to sit on the deck for the recommended amount of time specified by the manufacturer. This will give the solution time to penetrate and loosen dirt, mould, and mildew for easier removal.

Rinse Thoroughly: Once the cleaning solution has had time to work its magic, rinse the deck thoroughly with clean water. You can use a water hose or pressure washer for this step, but be sure to use a gentle setting to avoid damaging the decking material. Start from the highest point of the deck and work your way down to ensure complete coverage.

Repeat if Necessary: Depending on the level of dirt and staining, you may need to repeat the cleaning process for stubborn spots or heavily soiled areas. Simply reapply the cleaning solution, scrub as needed, and rinse thoroughly until the desired results are achieved.

Allow to Dry: After rinsing, allow the deck to air dry completely before replacing any furniture or accessories. This will prevent moisture from getting trapped beneath objects and potentially causing mould or mildew growth. Depending on the weather conditions, drying times may vary, but typically, the deck should dry within a few hours.

Apply Protective Finish (Optional): If desired, you can apply a protective finish or sealer to your composite decking to enhance its durability and resistance to stains, fading, and moisture. Be sure to choose a product specifically designed for use on composite decking and follow the manufacturer’s instructions for application.

By following these steps, you can effectively clean your composite decking and restore its beauty and functionality. Remember to schedule regular cleaning and maintenance to keep your deck looking its best year-round. With proper care, your composite decking will provide years of enjoyment for you and your family.
