Applications
Use for post-installation residue or mineral buildup on compatible ceramic, porcelain, quarry tile, sanded grout, concrete and masonry. Textured stone requires particular care: acid can etch, lighten or change its color even when the surface is not polished.
Selection and Use
- Check the substrate’s acid resistance and perform a test patch. Do not treat polished stone as an approved surface. Let new grout, concrete and masonry cure before cleaning.
- Prewet with clean water, work in small sections and agitate with an acid-resistant brush. Extract the residue, rinse thoroughly, then follow the label’s neutralizing wash with Tile & Stone Cleaner.
- Protect nearby metals, wood, carpet and landscaping from both liquid and vapors. Do not mix with ammoniated cleaners. Follow the label and safety sheet for protective equipment and ventilation.
