I have a customer with hard water stains on one corner of their house where the irrigation systems hits it. The catch is that he has a colored brick and mortar house. Some threads suggested muratic or even a wire brush. Is there a chemical out there that will not effect the brick and mortar color? I forgot to take pics while I was there. It is a whitish brick and a chocolate color mortar. Thanks!
