I have a customer with a new pool, less than 12 months old. The oak trees seem to be dropping debris and staining the concrete. I washed it today with a commercial concrete cleaner with no luck. Also tried wood brightener and had no luck. Any ideas on how to remove these stains? I’m trying to avoid any muriatic acid due to the damaging effects it has on the concrete.
