Herbicide staining on vinyl fence (pendimethalin).
Lawncare company said they used this (Pendulum Aquacap), and it left yellow dots all over a white vinyl fence that they subcontracted me to clean. They have been there for about a week or more. I had bleach and a degreaser with me, but they didnt seem to have any effect. Do you guys know of a chemical that can remove the yellow staining?
