How to Clean and Maintain Composite Decking

Composite decking is a popular choice for outdoor areas due to its durability and low-maintenance finish. However, to keep your composite deck looking great and extend its lifespan, you must clean it regularly.

In this blog, we’ll discuss the best way to clean and maintain your composite decking.

Step 1: Cleaning Supplies

Before you begin, gather all your cleaning supplies. You’ll need a soft-bristle brush, a composite deck cleaner or mild detergent, water, a hose, a sponge and a bucket.

Step 2: Clear the Deck of Objects

Remove furniture, plants and BBQs from the deck. This will give you access to the entire deck without having to clean around furniture.

Step 3: Sweep the Deck

Use a soft-bristle broom or leaf blower to sweep off any loose dirt, leaves or debris from the deck. You must have a clean surface to effectively clean your deck.

Step 4: Prepare the Cleaning Solution

Pour either a mild detergent or composite deck cleaner into your bucket. Fill your bucket with water and ensure the detergent and water are mixed.

Note: Follow the ratio on the deck cleaner to ensure you have the correct solution.

Step 5: Apply the Cleaning Solution

Dip your soft-bristle brush in the cleaning solution and gently scrub the composite decking boards. Pay extra attention to visible stains or mildew growth. You can use your soft sponge here to lift off dirt from hard-to-reach areas or stubborn stains.

Step 6: Rinse the Composite Decking Thoroughly

After scrubbing, thoroughly rinse the deck with clean water. You can use a garden hose, or a pressure washer to remove the cleaning solution. Note: If you use a pressure washer, ensure it is set to a low setting with a fan-tipped nozzle. The nozzle should be more than 30cm from the deck surface when sprayed to avoid damaging the composite decking.

Step 7: Regular Maintenance

Aim to clean your composite decking at least twice a year, preferably at the beginning and end of a season. Regular cleaning of your composite decking is the key to a like-new deck for many years to come.

Step 8: Protect Your Composite Decking

To maintain your composite decking’s longevity, consider using protective mats to prevent scratches. Also, avoid dragging heavy objects or furniture across the deck to prevent damage.

Simple Cleaning Routine

Weekly sweeping is essential to prevent the build-up of dirt, debris, and potential mould and mildew growth. Don’t forget to sweep under pots or furniture.

In addition, gently scrubbing your deck with detergent and water a few times a year is essential to keep it looking new.

Clean Up Spills Quickly

Food spills are common on outdoor decks, especially oil and sunscreen stains. Quick action is key to preventing stains and potential damage. We recommend using BBQ mats, rugs and plant stands for extra protection.

Selecting the Right Cleaning Products

Using a mild soap, sugar soap or composite decking-specific cleaners is recommended as they offer a gentle formula that will not damage the decking surface. Brushes must have soft bristles and be used in the direction of the grain to prevent scratching the decking.

By setting up a simple cleaning routine, clean up spills quickly, choosing the right cleaning products and maintaining a cleaning schedule, you’ll ensure that your composite deck looks like new for years to come.
