We all use our taps every day, whether that’s for bathing, doing dishes or having a glass of water. But not everyone thinks that much about the kind of water that comes out of the tap. But if you have very hard water, you have no choice but to think about it, whether that’s because of residue on your drinkware, on your faucets, inside your electric kettle or pretty much anywhere water comes in regular contact. The hardness of your water depends largely on where you live. Fortunately, hard water has no known negative health ramifications, and may actually present health benefits. Unfortunately, hard water can be a nuisance when it comes to cleaning, and it can negatively affect your pipes, water heater and other equipment. If you’re wondering how to remove hard water stains, we’ve got the rundown (plus the products you need).
What Is Hard Water?
First, it’s worth explaining what, exactly, hard water is. According to USGS.gov, water hardness is the result of dissolved calcium and magnesium in the water, in addition to some other deposits. The difference between hard water and soft water isn’t exactly a binary, but rather a scale measured in milligrams per liter, with levels ranging from soft (0 to 60 mg/L), moderately hard (61 to 120 mg/L), hard (121 to 180 mg/L) to very hard (more than 180 mg/L).
Water becomes hard as it passes through deposits in the ground. This affects most Americans — 85% of the country has hard water. Since minerals are essential for health, drinking hard water can actually have a positive impact, as it can be a supplemental source of minerals. However, hard water can leave a slick residue on your hands after you wash in the sink, in addition to negatively affecting appliances and pipes through scale buildup. And of course, those pesky white spots are often a result of hard water.
How To Remove Hard Water Stains Using DIY Methods
Cleaning hard water deposits is an extra step in the routine, but it doesn’t have to be difficult. If you’re wondering how to remove hard water stains, you can buy cleaners or make a solution at home. In fact, you can do a lot with just a spray bottle filled with a solution of distilled white vinegar and water. But sometimes you want a little extra muscle to tackle hard water issues. Here’s how to remove hard water stains using products you have at home.
How to Remove Hard Water Stains with Vinegar
One way to remove hard water stains is to create a 50/50 solution of vinegar and water and put it in a spray bottle. Spray the solution on affected areas, and allow it to sit for at least five minutes. You might want to open your windows to do this; while vinegar is non-toxic, it does have an intense smell. Then, simply use a nonabrasive sponge, brush or squeegee and wipe the surface with a wet towel.
How to Remove Hard Water Stains with Baking Soda and Vinegar
For tougher stains, you can use a combination of baking soda and vinegar. Spray the affected area with a vinegar-water solution first, then follow it up by mixing a solution of water and baking soda. It should form a thick paste, so add more baking soda or water as needed. Then apply it to your surfaces and scrub with a towel.
