ABF Restoration Detergent 5 GALLON (formerly Glazed Surface Rest “GSR”)
Originally designed for glazed brick and terra cotta cleaning, ABF offers the strength of HF but with a higher degree of safety. ABF has the ability to work well without having to cover glass when used as directed. ABF’s acid blend is more effective than HF at removing the black stains that occur on glazed brick with almost no chance of burning. ABF is our most economical restoration detergent.
