"THIS WILL NOT HARM THE PRDUCTS.IF YOUR HOUSE WAS GLASS IT WOULD STILL GROW MILDEW ON THE NORTH SIDE.SO THEREFORE CLEANING TREX OR OTHERS SHORE BEATS STAINING, CRACKING AND WARPING AND SPLITTING."
This is also a bunch of garbage 2 weeks after my deck was installed everything you have metioned above began to happen. Also, the new batch I just received isn't even out of the bundle and I can already see the boards are warped, cracked, and splitting. I will never buy from Trex again, this company must offer you a class in lieing.
