heavy-duty cleaner is chemically designed to remove heavy soap scum, body and tanning oils, mineral deposits and other soils found in all areas of the restroom. It is effective on tile and grout surfaces, countertops, sinks and toilets. High-foaming action allows longer contact time and maximum penetration of tough soils. Use green earth restroom cleaner on acid-resistant surfaces such as showers, bathtubs and other restroom surfaces. It leaves a pleasant, powerful fragrance. Do not use on marble, aluminum, terrazzo, formica or carpeting.
