We spent the extra money to put in a pretty large Trex deck 2 years ago. I have had to clean the deck 3 times now due to the mold with the last time being less than a month ago. The mold is back again. I had contacted the company to see what to use to clean the deck and found the Corte Clean that was recommended. I was told that I should only have to clean it 2 times a year... what a joke. I am totally dissatisfied with the deck as it was sold to us with the claim that it would be low maintenance. I guess that only applies if you don't care what your deck looks like. I wish we had just kept our concrete patio.

There is a current lawsuit in CA for mold and mildew issues (black spots). Please contact and join.

Also, for the flaking and warping issues, Trex acknowledged there was an issue. The link to the classa action lawsuit is

Keep up the fight, don't let anyone tell you otherwise. I hope this information helps.

Bleach is horrible for composite decks (and the environment). The previous posts in other forums here about bleach 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 ( Works for several years and recommended by some big deck manufacturers for remove mold, mildew stains from a composite deck. Like one of the previous members, we are working to create awareness that bleach is bad for composite decks and docks.
