I found out about Corte Clean from my father-in-law, who use to own a house with a composite deck. We use to order it together. I have a 12 X 14 second story Timbertech deck with stairs down to the ground level in New Jersey. It has lots of trees around it and gets mold. I take the pressure washer to it to remove them, then use Corte Clean. I do this twice yearly, in the spring and fall. I have been using Corte Clean for 10 years. The deck still looks brand new, excluding where it wasn't properly installed with proper drainage gaps.
