If we are not supposed to wash the roof , why are products made to do this? My older unit came with instructions to wash with Dawn Concentrate not the scented dish washing liquid.
I wash mine at least twice a year and it has not caused any problem that i can see. Maybe the newer EPDM is different from the older EPDM?
