HEY GUYS DOES ANYONE HAVE ANY IDEA HOW TO REMOVE BLACK S0OT FROM VINLY SIDING.. I HAVE TWO CUSTOMERS WHO HAVE CHIMNEYS THAT COME OUT FROM THE SIDE OF THEIR HOUSES THANKS IN ADVANCED
We cleaned a house where there was a puff-back and he had smoke from his oil furnace leave soot on his gable vents. It was only a month later and we cleaned with SH and turned out fine. Don't oversell. There is a good chance that stain has been there a long time and has soaked into the vinyl. Also try BT200
