We get black mold spots on our composite deck. I have two types of composite decking, as we extended the deck. It's about 400 square feet total in Iowa. This is my 4th time purchasing Corte Clean. I tried some old Corte Clean and it didn't work. I noticed the date was expired from 2018. Fresh Corte Clean works pretty darn good! I just bought two more today.
