ok guys heres 1 for ya,I have a customer with an exposed aggragate(brown peagravel) driveway that was poorly finished by the concrete finishers about 8 months ago and thay didn't wash it very good when thay finished the driveway and there is alot of dried and set concrete in different places also the whole driveway has a white film over the peagravel again from poorly cleaning in the first place,My question is what would be the best cleaning product to use to get this film off and take a little more concrete off(poss. diluted muratic acid?) so I can put a real good tinted uv protectant sealer on. thanks to all.
