Ultra Chem Labs' Bathroom & Grout Cleaner is one of the top tile and grout cleaners on the market. This professional strength cleaner is designed for extended retention on vertical surfaces, meaning that it will cling and adhere to tile walls and the sides of tubs and toilet bowls. Ultra Chem's Bathroom & Grout Cleaner contains food grade acids that enable it to safely and effectively remove hard water stains and mineral deposits. It will outperform harsher, more toxic cleaners containing hydrochloric acids and phosphoric acids. Ultra Chem's Bathroom & Grout Cleaner also removes old residue on surfaces and soil deep in grout, all the while restoring the shine to tile and porcelain surfaces. To top it off, Bathroom & Grout Cleaner is Green Seal Certified so it is environmentally friendly.
