How do I remove any ground soil from the construction of my Trex decking?
A pressure washer with no greater than 3100 psi* that has a fan attachment/adjustment and soap dispenser may be used to remove soil, concrete dust, or other types of construction soil. Spray deck with soap, and then follow by gently scrubbing each deck board with a soft bristle brush. Spray/rinse each individual deck board using fan tip no closer than 8” from the decking surface. RINSE THOROUGHLY. If dirty water from cleaning is left to dry, this will cause a film to remain on the decking surface.
*Use of a pressure washer greater than 3100 psi could damage the boards and void the warranty.
