What kind of solution to clean trex? Do I use sh solution? Please tell me a ratio of product to use that won’t damage this deck? ---

Trex is fundamentally 1/2 recycled wood fiber and 1/2 recycled plastic. If using 12% SH, a “50/50” mix is 6% SH, way too strong for the wood fiber content. Even if 6% is used, still too strong of a mix. Wood is “held together” by complex organic polymers called lignin. SH above 2% or so will start to break down this natural wood “glue”. ---

Exactly. We DS trex. Then use a very light fan tip to go over it ---

Good morning all, Stupid rookie question here and I was thinking about. when washing a house right up against a deck, how would you stop the deck part next to the house from not getting clean from the house wash solution you use and then you have a clean deck next to the house and the rest dirty. I know ideally you would want to clean both but in situations where the customer just wants the house washed. ---

Pre-wet your deck when you get to that area and keep wet and then rinse well when you rinse the house. ---

Is a HW mix ok to use on newer Trex? Wet, treat, (scrub if needed) and rinse? ---

HW mix will do the trick, no scrubbing needed. Lay down the mix, give it 10 minutes then come through with medium pressure ---

Make sure not to use too much pressure or it will get white specs in Trex and look worse. Easier is better. Let the chems do the work and rinse lightly ---

just like said below. Unless really dirty, then can use stronger mix, but 95% of them HW mix will do the trick.
