Where Else Does Hard Water Affect Us

Hard water sediments can also carry potentially harmful bacteria along with them; research done in 2014 found hard water scaling is directly responsible for bacterial growth in residential drinking water. If your home gets water from a well, you most likely have hard water, and up to 85% of homes or buildings across the country are likely to have hard water in their taps. Hard water problems can be a real hassle, especially for new homeowners who may be unfamiliar with the issues it causes. Here are just a few problems that hard water causes in your home:


Clothes look dingy, worn out, and don’t feel or smell clean.

Some research estimates that clothes that are washed in hard water last almost half as long as other items washed in filtered or softened water.


Skin and hair irritation and damage.

Washing your hair in hard water can cause build-up that makes it tangle easily, look dull and feel rough. While showering or bathing in hard water with soap can leave a film on your skin, which can prevent the removal of dirt and bacteria. This film can also irritate skin, especially sensitive or younger skin.


Soap scum build-up.

Hard water prevents soap from cleaning and dissolving completely. Instead, the soap bonds with the minerals in the water to form a film that sticks to everything and causes a soap scum ring in the bathtub or toilet.


Cleaning feels next to impossible.

The hard deposits left behind after hard water dries are called limescale, a mineral that is incredibly difficult to remove and can even cause chemical reactions that make cleaning products less effective.


Permanent damage to glass fixtures.

Mineral deposits can become so bad that there is a chemical change that permanently damages glass material. For example, if you have a glass shower door with a white, cloudy residue that never seems to come off completely, those stains are likely permanent because the chemicals in your hard water have etched the glass and permanently ruined the finish.


Plumbing and appliance damage.

Plated plumbing fixtures discolored by mineral buildup are often beyond restoration because the chemicals eat through the coating. You may see mineral build-up around drains, faucets, and on shower heads, as well as in common appliances like dishwashers, coffeemakers, and more. These deposits can damage the rubber washers that seal the fixtures, creating leaks that can cause even more damage.

Solving those problems

can vastly improve your family’s quality of life and get things back to normal again. It can also save you some serious cash- it’s estimated that hard water can cost property owners upwards of $800 a year. No matter your situation, finding a solution to your hard water problems is essential to achieving your healthiest and happiest life.




  1. Great article. I’ve always wondered how to get those pesky stains out of the toilet. Now it makes sense on how they are created in the first place. I guess it makes sense to know where the stains come from in order to know how to clean it.  

    I just bought another crock pot because my old one cracked. Not sure how that happened, but I noticed that I got some baked on stains already by the second use. I’m definitely going to try your cleaning methods. I’ll let you know how it works.
