Polished Stone Cleaner (PSD)’s unique chemistry is a neutral cleaner with a lot of advantages for interior cleaning. It has a very mild odor and is non-corrosive. Non-hazardous components make it safe for both the end user and the environment. PSC is capable of removing smoke, heavy finger soils, sealers and polishes and foot traffic soil without any harm to the marble substrate. Another benefit is that the product does not foam on pick up, so if you must vacuum residue you will not waste time clearing foam. All these characteristics make the soap readily disposable into sanitary sewers or easily treated in waste reclaim systems.
