Streaks
John,I have tried IG Pink up to and including full strength without successfully removing black streaks caused by pollution. I have also tried citrus-based cleaners and full strength Simple Green. Nothing seems to work except Soft Scrub with bleach. I hate to use the stuff because it is abrasive, tough on the hands and near impossible to totally rinse off. I always have a residue after the surface dries. I am sure it removes IG products too… So, I spent hours applying the IG products and getting the boat looking just so only to have a month’s worth of rain leave black streaks that won’t come off without removal of the IG also.Any and all recommendations are welcome.
