It effectively removes cement film residues, efflorescence, oxide stains, and construction-related deposits left after tile installation. The fast-acting formula penetrates stubborn contaminants and restores the original appearance of tiled surfaces. Suitable for both interior and exterior applications, it can also be used as a general-purpose cleaner on acid-resistant surfaces. The product is easy to apply and ideal for post-construction cleaning and maintenance of ceramic tile installations. It should not be used on acid-sensitive surfaces such as marble or terrazzo.
