If I strip and their is Trex mix then I just keep the trex wet to dilute the chemical. Now if I am just cleaning the trex, I just rinse the wood after the application. We usually just use bleach on trex followed by the after care product recommended by trex. I have never had a problem with discoloration of trex.
Actually I should mention that we do not powerwash the wood with PSI but just use the GPM of the machine to rinse. Trex looks nice when it is washed and then sealed with the after care product. Reminds me of armor all with a crayon smell.
Pretty damm cool Dave glad to see recycled plastic and sawdust being put to good use!
I personally like the look and feel of Choice composite decking rather than Trex.I have one composite deck i clean and stain every year with my Gray Away Brown tone.It looks just like they do when first installed.I also only clean with bleach/soap on my composite jobs.
I just received a call from a builder who I do work for all the time. He asked me to clean a composite deck (newly installed) said there is dirt and grime on it. I do not know what brand it is and neither does he (contractor who installed disappeared). After researching composite decking, I was thinking about using a mild detergent and a brush or rotary scrubber. Any suggestions would be greatly appreciated. Thanks.
The composite decking to be cleaned was on the floor of an enclosed sunroom/florida room. Sweep it and then scrubbed it with a mild detergent. Came out beautifull... for the most part. Someone dropped stain on the decking (grey decking) and it now has a few dark spots from walnut stain on it. The manufacturer is GeoDeck... I called them for tech support... (wanted to follow their recommendation so their is no breach of warranty) and I am still waiting for a return call. Any suggestions on the dark spots of stain?
Thanks for the info WoodSaver... went back to the site with chemicals in hand, to find that the painter who droped the stain tried to "sand" it out like you would a wood deck! Really looks horrible now! Needless to say, I am out of the loop now. His liability, not mine (thank goodness).
