Hard water stains, primarily calcium and magnesium deposits, can mar the appearance of granite surfaces. These unsightly marks are left behind when hard water evaporates, leaving a mineral residue that bonds to the granite. A common example is the white, chalky film often seen around faucets and sinks.
Maintaining the aesthetic appeal and longevity of granite countertops is paramount. Addressing hard water stains promptly prevents them from becoming deeply embedded and more difficult to eliminate. Furthermore, removing these deposits ensures a clean and hygienic surface, crucial for food preparation areas.
