Composite decking is a popular choice for homeowners because of its durability, low maintenance, and clean aesthetic appeal. Made from a combination of wood fibres and recycled plastic, composite decking has several advantages over traditional wood decking, including resistance to rot, insects and warping, but like any outdoor surface, it will get dirty over time. 

Without regular cleaning and maintenance, the longevity and appearance of your composite bonding will be compromised, but improper cleaning can be equally as damaging. In this article, we’re going to discuss how to properly clean and take care of your composite decking to keep it looking its best for years to come.

Common Issues Affecting Composite Decking

Composite decking is generally a great choice for outdoor spaces, but it can be susceptible to common issues that can impact its appearance and compromise its integrity. Some of the most common issues include:

  • Mould and mildew growth
  • Water stains and food spills
  • Grease marks
  • General dirt and debris accumulation

These issues not only make your decking look dirty and unattractive, but they can also lead to discoloration and even structural damage if left unattended.

Preparing for Cleaning

Before you start the cleaning process, it’s important to remove any furniture, potted plants and other items from your decking. This will allow you to clean the entire surface thoroughly without any obstructions.

After you’ve cleared your decking, make sure you have the following items for cleaning: a broom or brush, a bucket, warm water, mild detergent, a soft bristle brush, and a garden hose.

Sweep the Decking

To begin, sweep your composite decking with a broom or brush to remove loose dirt, leaves and any other debris. This will get rid of the majority of the surface dirt on the decking and make it easier for you to do a deep clean. 

Rinse the Deck with Warm Water

When your decking has been swept, rinse it thoroughly with warm water. This will help to loosen any remaining dirt leftover from the initial sweep and make it easier to scrub off harsh stains.

Scrub and Remove Dirt and Debris

Using a soft bristle brush and a mixture of warm water and mild detergent, scrub the surface of your composite decking to remove more stubborn dirt, stains and debris. You may find it easier to work in small sections. Take care to only apply gentle pressure so as to avoid damaging the composite decking. 

Rinse Your Deck Thoroughly

After you’ve finished scrubbing, rinse the deck with clean water. Make sure to rinse thoroughly to avoid leaving any residue on the surface.

Can I Use Bleach to Clean Composite Decking?

While bleach can be effective in removing stains and mould from some surfaces, it’s not recommended for cleaning composite decking. Bleach can discolour the decking and cause long-term damage. Make sure to only use mild detergents or specialist cleaners that are specifically formulated for composite decking.

Can I Use a Pressure Washer to Clean Composite Decking?

As a rule of thumb, it’s best to avoid using a pressure washer to clean composite decking. The high-pressure water stream can damage the surface and strip away the protective coating. That being said, if your decking has harsh staining and you want to use a pressure washer for a deep clean, always check the manufacturer’s guidelines first and adjust the pressure to a lower setting to prevent any potential damage.
