 It will. It will. And I want to just kind of add this. So the wet and forget when it's sprayed, if the mold and mildew and the fungus and algae was still there, it would take at least six weeks to kill that. It's a slow, it's a complete kill. And next year, it'll kind of be gone most of the time, but it'll start growing back in the following year. You'd have to reapply to kill it.
