Frequently Asked Questions
Why is my composite deck slippery or discolored?
Algae, mold, and mildew often build up in shaded or damp areas. These can make the deck slick and cause discoloration if not properly cleaned.
Can power washing damage composite decking?
Yes. High-pressure washing can cause surface etching or remove protective coatings. Soft washing gently lifts contaminants without abrasion.
What’s the best way to clean Trex or other composite brands?
Our proprietary soft washing solution is safe for all major composite brands like Trex, TimberTech, and Fiberon and delivers a deeper, longer-lasting clean.
How often should a composite deck be cleaned?
We recommend professional cleaning every 1–2 years, depending on exposure to shade, moisture, and foot traffic.
