Abstract
An acid-based cleaner and related methods, for cleaning and treating tile, limestone-based cement and concrete and similar surfaces to maintain a slip-resistant surface, and to harden and strengthen the grout or cement and make it more resistant to penetration by salt or other deterious chemicals. The cleaner comprises an aqueous solution of hydrofluoric acid, phosphoric acid, and a surface active or wetting agent. Also, the invention, upon application to the surface, creates a microbe-free surface as required in hospitals, laboratories, and the like.
