C-E-R- Calcium and Efflorescence Remover

Quickly removes efflorescence, calcium, calcium carbonate, and hard water stains on concrete, masonry, stucco and a variety of other surfaces.  At 28% muriatic acid, C-E-R is strong enough to etch concrete at higher concentrations, and can be diluted down to use as a general purpose cleaner.  Contains buffering agents to help reduce corrosion to sensitive surfaces.  Always test in an inconspicuous area, to ensure desired results. Avoid contact with sodium hypochlorite!
