Does anyone know the best way to get Georgia red clay stains out of new concrete? Supposedly rust remover with oxalic acid does it but I'm afraid it may harm the adjacent new turf and plants.

hot water pressure washer might work. we just laid 1400 sq of patio on the back of this house and received a "bad" batch of poly sand. the entire bag had been filled with glue and no sand. not thinking this would ever happen, we dumped it out on the pavers to spread and pack and it stained the hell out of them. we had to get our hot water pw to get the crap off. still waiting for a check from the manufacturer to "make it right" like they said they we gonna do.
