It is aimed at calcium carbonate scale and at efflorescence.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe problem it solves\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCalcium scale is one of the more stubborn maintenance problems around a pool. It builds as a hard white crust on tile, stone and waterlines, and efflorescence pushes white crystalline deposits out through grout, coping and raised bond beams. Neither responds to normal cleaning, and scrubbing hard enough to shift them often damages the surface underneath.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat to expect\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe product is rated to remove roughly 2 to 4 mils of scale per application. That is a real number worth planning around: a light haze may clear in one pass, while years of hard water buildup will take repeated applications rather than one aggressive attempt. The maker describes it as environmentally friendly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHandling\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eFollow the label directions and the safety data sheet for dilution, contact time and personal protection.
