I had a customer call me that had their lawn maintenance company spray their pavers with a herbicide. They now have yellow stains on the pavers. The lawn company said it would fade away in a week or two, well it's been two weeks and the stains are still there.
I tried cleaning with my surface cleaner, no difference. Sodium hypochlorite no difference. Byutel/potassium hydroxide no difference,sodium hydroxide no difference, simple green no luck. Oxcillic acid no difference BARC F9 no difference.
I talked with the manufactures rep, he said to try Damn lemon scented dish washing soap. I will go back on Wednesday and try Dawn.
Has anyone ran in to stains like this and have been able to remove them?
