MB-1 Floor Amore is a highly concentrated, slightly alkaline detergent with a twist! It is rinse free and leaves no dulling film. Special organic salts in its formula act as "moisturizers", thus preventing the natural stone from "drying out". It also contains optical brighteners to enhance the finish of the surfaces on which it is used and maintains a natural, streak free look. Originally designed for marble and granite, it is gentle enough to be safely used on hardwood, ceramic, resilient tile and any other hard surface not harmed by water.
