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!
