Nontoxic and phosphate-free cleaner removes difficult stains from ceramic tile floors and grouting. Enviro mix packaging allows you to accurately and easily mix concentrates with a built-in measurement system in a designated spray bottle (sold separately). Simply squeeze and fill the upper chamber with concentrate to then pour the cleaner into your spray bottle (sold separately) and fill with water for easy cleaning.
