If you add sodium hydroxide, does it shorten the life of the EBC?Never used it on gutters. Recently used it on a parking garage clean and tested it against a sodium hydroxide/butyl mix... EBC was significantly better at emulsifying oil spots after spraying on with pump up. Sprayed 50/50 EBC/Water mix and dwell for 5 mins, went back to spray again and you could see spray dislodging oil.
Tested with 1 gallon of EBC mix (50/50 with water again) and 1cup of sodium hydroxide flakes... This yielded the best results on oil spots.
