Hello everyone, I’m a little green to chemicals and I got a lead to clean a concrete pad about 11 months old that the customer try to clean with clorox bleach about 2 months ago and left stains. I’m not sure if re applying sh again will even it out or if I need a more specialized chemical
If it were me I would reapply with 3% and surfactant making sure the surrounding plants are protected then surface clean as usual
