Composite decking is a popular alternative to traditional wooden decking. It is more durable than treated lumber and will last much longer with proper care.

But it’s easy to make mistakes when cleaning composite decking. If you use the wrong type of cleaning solution, you risk staining the deck boards. You could also destroy the waterproof seal that gives the deck its durability.

If you’re considering adding a composite deck to your home, you’ll want to avoid making beginner’s mistakes in caring for it. With that in mind, we have created a guide that will tell you exactly how to clean composite deck boards. 

Sweep the Deck First

Before you begin washing your deck, sweep the surface with a broom to remove dirt and debris that is sitting on top of the deck. This will prevent any excess dirt from getting embedded in the grain of your composite decking.

Make sure to remove any furniture, plants, or other items from your deck before getting started.

Use a Hose to Rinse the Deck

After you finish sweeping, use your home’s garden hose to give the deck a quick rinse. This will save you some energy later when you’re scrubbing the deck.

Apply a Mild Cleaning Solution

The number one mistake many composite deck owners make is using a harsh cleaning solution. This can severely damage composite deck boards. Never use chlorine bleach, which will eat into the sealant on your decking.

Trisodium Phosphate is commonly used to clean wooden decking. But, it will cause stains and discoloration if you use it on composite decking.

Instead, aim for cleaners that are less stringent. Most of the best cleaners for composite decking can be made from items you have around your home.

You can make a simple, mild deck cleaner by mixing dish soap (Dawn) with water. Another option is to mix a solution of vinegar, baking soda, and water. If you do this, let the mixture soak into the deck for 20 minutes before rinsing.

Scrub the Deck With a Soft-Bristle Broom

Always use a soft-bristled brush or broom when cleaning composite decking. A broom with hard bristles has the potential to scrape or scratch your deck boards.

With the cleaning solution still on the deck, scrub the entire deck with your broom to remove dirt and grime from the grooves in the deck. Make sure to sweep with the grain to ensure the most thorough cleaning. 

Rinse With a Hose or Power Washer

When you’ve finished scrubbing, use your garden hose to rinse the debris off the deck. You can also use a power washer as long as it has a wide nozzle and a PSI lower than 1,5000.
