The standard method for cleaning a composite deck involves using a gentle brush and water to scrub away accumulated dirt and residue. For early-generation composite decking, stubborn dirt may require the use of a composite deck cleaning solution before scrubbing to lift dirt from the surface effectively.

For high-performance composites, which incorporate shell technology, you can simply use warm soapy water and a soft bristle scrub brush. After scrubbing, a final rinse with clean water completes the cleaning process for both composite types.

If you’re struggling to clean your deck with a soft brush, a power washer can assist with the cleaning process. Just ensure that the power washer falls between 1500-3100psi and that you’re using a fan nozzle at a distance of at least 8 inches from the deck surface.

The best way to clean a composite deck is to periodically clean it throughout the year to ensure a vibrant appearance year round. Typically, a bi-annual cleaning schedule is sufficient for cleaning a Trex® deck and keeping it looking new. Decks exposed to heavier soiling may require more frequent cleaning.

Best Cleaners for Composite Decking

Knowing what to use to clean composite decking is crucial for preserving its appearance and durability over time.

The cleaning approach will differ depending on whether your deck is early-generation or high-performance Trex composite decking. Early-generation composite lacks the protective shell found in the latter, requiring a specific cleaner such as Deck Brightener and Wash. High-performance composite decking can be effectively cleaned with warm, soapy water or soap added to a power washer.

It’s important to note that many deck cleaning liquids, including composite deck cleaner, contain chlorine, which acts as a bleaching agent that can affect older types of composite decking material. It’s important to use the correct cleaning products and apply them carefully and promptly to preserve the deck’s aesthetics and strength.

Why You Shouldn’t Use DIY or Homemade Deck Cleaners

Using DIY composite deck cleaner is not recommended due to its potential to cause irreversible damage to your composite decking. Products containing substances like solvents, high-concentration chlorine, and abrasive cleaning agents can deteriorate composite surfaces, leading to compromised structural integrity and a severely diminished aesthetic finish.

Avoid using DIY composite deck cleaners and instead opt for cleaning solutions specifically formulated for composite decking. Or make your life easy and simply use warm, soapy water. The risk associated with using composite deck cleaner, homemade or DIY, is too significant to ignore, especially when this may put your warranty at risk. For optimal results (and to make sure you uphold the longevity and appearance of your deck), it’s best to use manufacturer-recommended cleaning products.
