Is mold still an issue with Trex? Does all composite decking have their problems? We are just days away from building a new deck, when I came upon this site. I fear doing it with composite material now.

Bleach is horrible for composite decks (and the environment). The previous posts about it and oxalic acid are pretty accurate. I am a chemist and work with composite decks. You may create a worse problem than you had and possibly ruin your expensive deck if you use bleach or acids. Look for a non bleach cleaner. There are also treatments to help protect the deck from mold/mildew and other stains (dont use a coating/paint or you will be in for a lot of work every couple years). We love a product called resist mist for composite decks (www.resistmist.com). Works for several years and recommended by some big deck manufacturers for remove mold, mildew stains from a composite deck. The images in this post are exactly what the product was designed to help eliminate. Like one of the previous members, we are working to create awareness that bleach is bad for composite decks and docks.

I wish we knew about this stuff years ago... We are here in sunny Florida and the mold on our deck was absolutely out of control! After a last ditch effort, we contacted a company, Rhino Hide, that Trex recommended. They have a non-bleach cleaner and a protectant to prevent mold from coming back. This stuff literally saved us from replacing the whole deck. I'm not sure if it will help with the chipping but it worked miracles for our mold problem...
Best of luck to you all.

BV005253, it so apparently obvious to all that you either work for or have an interest in the Trex products. I have been a general contractor in California for 20+ years and it is a known and ongoing joke in the industry that Trex is crap. No contractor I know installs this stuff. So stop lying and helping this company intrap more victims

We have Trex decking that is 12 years old now and we wish we never bought it. It is faded, covered in some kind of white solid "stuff" underneath the deck, and it has swollen which in turn has caused all the pressure treated joyces to rot. This product gets so hot in the Summer that you can burn the bottom of your feet and it smells like burning plastic.

I finally gave up and used a combination of bleach and bathroom cleaner sprayed on and then cleaned within 5 minutes using a power washer. The results are perfect. There is no fade on the surface and I finally got ride of all the black mold that I could not get ride off just power washing for the last three years. My deck is partially covered by a portico and faces east but is also shaded by some tall trees so I don't get a lot of long direct light. Live in North NJ. I found this solution the best> I also have a boat and mold and mildew cannot be removed with out the use of a bleach based product even on vinyl interiors

Initially started with mildew and black mold. I wasn't able to clean it completely and the deck looked like the color was bleached out. In addition, the deck has a orange colored fungus looking growth. it seems like it is growing from within. It not removed immediately and if allowed to dry, you need a putty knife to scrape it off. I ended up painting the deck in hopes to seal the surface. In part it worked, but wherever I missed like areas by the deck screw, the fungus will grow. I contacted Trex and filed a warranty claim. Now I'm waiting to hear from them.
