How do you get rid of hard water stains? Vinegar is a safe, all-natural household cleaner with the amazing ability to combat hard water stains. Pour some in a spray bottle and squirt any surface where you find hard water stains. Let it sit for five to 15 minutes to give the vinegar time to break down the minerals in the chalky, white stain.
What are hard water stains made of? If your home relies on hard water, you’ll inevitably run into hard water stains. These stains are made up of minerals found in hard water, with some of the most common being lime, silica, and calcium.
Why do hard water stains occur? When hard water dries on surfaces, especially glass surfaces like windows, doors, and dishes, spots will most definitely leave marks. As previously mentioned, as hard water evaporates (versus getting wiped clean and dry), the minerals in the water are left behind, creating a hard water stain.
Do hard water stains go away? “I have found that spraying a mixture of white vinegar and water onto the stained area, letting it sit for 15 minutes, then wiping it away will usually get rid of a hard water stain,” Nogales-Hernandez says.
