Calcium Build Up & Scum Line Remover- Guardian Pool Tile Cleaner 2 qts. - Non-abrasive Save Elbow Grease 32 Fl Oz (Pack of 2)

- Targets Calcium - watch it find calcium you can't even see. Watch it reveal scale you can't even see. As it works, Guardian causes scale to turn brighter and whiter. Scouring or scraping never removes 100% of deposits. Guardian targets them, even on textured and uneven surfaces. - Pumice stones can take hours and easily take up a Saturday - Guardian works while you do something else. Spray on scaled surfaces & leave it. Removes scale progressively (see photos). Apply weekly until scale is gone. Heavier scale will take more applications. This is an "above the waterline" treatment. Also breaks down scum line. - SCOURING TILES WEARS OUT YOUR ARMS ? save your arms/shoulders & let Guardian work at the chemical bond level to remove calcium. NON-CORROSIVE ? Contains no harsh acid that can damage surfaces. NON-ABRASIVE ? pumice stones can scratch tiles and even remove numbers. Guardian won’t do that. - SAFER TO USE ? will not affect pool chemistry, contains no phosphates or brighteners. Designed to Federal BioPreferred Standards. NOT RECOMMENDED for use on porous surfaces like natural stone and cement tiles. - Save $100's compared to professional removal services. - Made in America.
