A big change from the past...
I used this stuff last year after pressure washing my White barrel tile roof on my Florida house. I only had one gallon, and that's not nearly enough to do my house. One year later, guess which section of the roof needed no cleaning? While the rest of the house suffered from black mildew. I also applied a little to my sidewalk and entryway. They also remain 100% clean and nice looking after 1 year. A big change from the past, where the sidewalk needed pressure washing every 3 months.
