I had tried several of the deck cleaners available through my home center only to be very disappointed in how they performed on my 1 year old Trex decking. The Corte Clean easily outperformed all the others I tried. I did not need the use of a pressure washer or did it require anything other than mild scrubbing with a deck brush. After seeing a You-Tube clip on Corte Clean I ordered 6 lbs and was pleasantly surprised as it worked exactly as described. All without using harsh chlorine bleach! Something we very much wanted to avoid around our lawn, flowers and landscape. An eco-friendly product that out performs in terms of ease of use and cleaning performance!
