So one of my guys cleaned a driveway that's about 1.5 years old the other day and everything went fine. There were some leaf tannin stains at the entrance so he hit those with 12.5 out of a pump sprayer like normal collected a check and hit the road. A few days later the homeowner sent me a picture of these wet-looking spots. This is where the the tannin stains were and he sprayed 12.5. Has anyone ever seen this? I have not.
