white concrete after what appears to be muratic acid


Colt, FYI F9 BARC will remove those HCL acid burn stains and it contains no Hydrofluoric or hydrochloric. Much less dangerous to you. We have concrete coating companies using it because after they use HCL to acid wash concrete in preparation for their coatings it runs down the sidewalk. They use F9 to reverse the orange. It takes a very little amount too.
