Had the same problem in a dairy building. There is an easy fix. Buy a gallon of muriatic acid and just pour it on a small test area and hose it off when you have determined the time is right. It will take the glaze off and make it very rough if repeated. The acid is inexpensive, but vapors are nasty!
