Spring is the perfect time to give your composite decking an in-depth cleaning. Composite decking is known for its durability and low maintenance compared to wood decking, but it still requires some care to keep it looking its best. Made from a blend of wood fibers and plastic, composite lumber or decking is designed to mimic natural wood while offering greater resistance to weather, stains, and fading. Over the winter months, your deck can take a beating. Let’s take a closer look at a few essential tips for cleaning your composite decking this spring.

Materials and Preparation

Before you start cleaning composite decking, ensure that you have all the necessary materials, including:

● Soft-bristle brush or broom

● Garden hose or pressure washer set to low

● Bucket of warm, soapy water or composite deck cleaner

● Rubber gloves if using a chemical cleaner

● Safety glasses

Once you have all of your supplies ready, you need to clear the decking area of furniture, grills, and other outdoor items to provide an unobstructed surface for cleaning. It’s also advisable to wear shoes that have non-slip soles to avoid slipping and falling.

Cleaning Process


● Begin by sweeping the deck with a soft-bristle broom to remove loose dirt, leaves, and debris. This prevents scratching the surface during the wet cleaning process.

Rinse With Water

● Use your garden hose to thoroughly rinse the decking, removing surface dirt and making the cleaning solution more effective. If using a pressure washer, remember to use it on a low setting to avoid damaging the composite material.

Apply Cleaning Solution

● For light cleaning, warm, soapy water works well. For more stubborn stains or built-up grime, opt for a specialized composite deck cleaner. Follow the manufacturer’s instructions for application. Typically, you’ll apply the solution and allow it to sit for a specified time

Scrub the Deck

● Using a soft-bristle brush, gently scrub the deck’s surface in the direction of the boards to remove dirt and stains. Avoid using a wire brush or anything that might scratch the composite material.

Rinse Thoroughly

● After scrubbing, rinse the deck thoroughly with clean water to remove all soap or cleaner residue. Leftover cleaners can attract more dirt or cause slippery surfaces.

Dry and Replace Deck Items

● Allow the deck to dry completely before replacing furniture and other items. This is also a good time to inspect the decking for any damage or issues that need addressing.

Dealing With Tough Stains

For tough stains like grease, oil, or wine, it’s critical to act quickly. Most composite decking materials have specific stain removal recommendations, so check the manufacturer’s guidelines. Generally, a degreasing agent or a solution designed for tough stains can be used. Apply directly to the stain, let sit according to the product instructions, then rinse thoroughly.


Regular maintenance can prevent deep cleaning and prolong composite decking life. Here are a few tips to help you keep your deck beautiful and safe:

● Spills should be cleaned up promptly to avoid staining

● Sweep regularly to prevent dirt and debris accumulation.

● Rearrange furniture periodically to avoid uneven fading.

● Inspect and clean your deck seasonally.

Cleaning your composite decking in the spring sets the stage for a great outdoor season. By following these simple steps, you can keep your deck looking new with minimal effort. Regular maintenance enhances the beauty of your composite decking and extends its life, ensuring that your outdoor living space remains a welcoming retreat for years to come.
