[RE-wrenches] PV scum from Dixie Fire

[Dan Fink]

Bill; Similar situation in my area (CO) from the big fire that went through
here last fall. Some had enough water onsite for the sprinkler trick, but
the biggest issue was thick coats of pink fire retardant from the slurry
bombers.
The only thing I could find that worked on both the ash/mineral scum and
the pink slurry was.....dish soap and soft scrub brush. And LOTS of
brushing, 3-4 times over all my PV arrays. I was hesitant to try anything
stronger, like Simple Green, and tried to get info on that and other
chemicals from a couple PV module manufacturers, with no success.
Good luck!
