Trex’s high-performance, low-maintenance decking makes it easier to enjoy your deck than maintain it. A simple soap and water cleaning twice a year is all it takes to keep your deck looking as good as it did on the day it was installed.
Using a broom, sweep off all the debris accumulated on the deck during fall and winter. For stubborn bits of debris stuck between boards, use a putty knife or screwdriver to clean the buildup gently.
Use a hose to rinse any remaining loose debris off the deck and prepare the surface for cleaning.
Trex composite decking features a high-performance shell that resists fading, staining, and mold. In most cases, a simple scrubbing with warm, soapy water and a soft-bristle brush is all that’s needed to retain a like-new appearance. For stubborn stains, use a composite deck cleaning solution.
Once you’ve finished scrubbing, rinse the decking thoroughly to avoid leaving behind a film or build-up. Hold the hose about 6-12 inches above the deck’s surface and spray a few feet before you. The water stream from a standard host should be strong enough to wash away dirt and debris. You can also use a pressure washer with high-performance composite decking products like those from Trex. The psi should be no greater than 3100 psi, and the fan tip should be kept at least 8 inches from the decking surface to prevent surface damage.
Check to identify any spots you may have missed and clean accordingly. Once complete, let your deck fully dry before use.
