Does Wet and Forget keep green mold stuff off? I see houses on my block with vinyl siding that has some of that green mold.

When we renovated our brick city townhouse in 1990 we added a two room addition and at the back of the house we were allowed by the historic code to use non-brick material. At that time vinyl was a standard, so that’s what we used. it never got the green moldy coating.
