I have been power washing houses for over 30 years. Full time in the summer .This is my 25th year in business and every year I receive more and more calls to remove artillery fungus (shotgun mold). I have tried steam (bad deal) soaps that have turned siding different colors, which I had to fix (which I did). I had tried bleach, soaps, acids, hand cleaners, paint thinner, nothing seams to take the black little dots off of houses. We know what it is. why can't we find something to take it off without doing some kind of damage. DOES ANYONE KNOW?
