If you have hard water in the home, it means that your H2O contains large amounts of minerals, such as limestone, calcium, and magnesium. It’s perfectly safe to use but it can have some pretty serious consequences on your house over time. A more serious problem is lime scale buildup which will eventually develop in your plumbing and impede proper water flow. But mineral-enriched water can also cause smaller troubles around the home: hard water stains. Whatever it touches can begin to spot and tarnish, including dishes, glasses, clothes, toilets, showers, sinks, and even your car. So it’s always a good idea to invest in hard water stain removal early on before it wrecks havoc on your entire house.
