How To Remove Hard Water Stains From Glass

how to remove hard water stains from glass

Let’s find out how to remove hard water stains from glass. A typical hard water stain will show up as a hazy, white spot on the surface of glass. If you have hard water flowing through your plumbing system, then you might’ve noticed nasty looking stains on your glass shower enclosure, tub or sink.

Unfortunately, hard water spots can form virtually anywhere water is used inside of your home. Depending on where you live, you might have high mineral content in your tap water.

Although the mineral content can make the water taste better, it can also leave unsightly stains on surfaces. If the hard water spots aren’t cleaned away, the minerals within the stain can permeate the surface and make it nearly impossible to remove.

Hard water is basically water that has a very high concentration of dissolved minerals. It’s likely to contain large amounts of calcium and magnesium. Since water is a solvent, it easily absorbs impurities, so as it moves through the ground, it grabs all sorts of different minerals.

The good news is that hard water isn’t bad for your health – in fact, it’s actually quite good for you. The bad news is that it will leave some ugly stains on glass surfaces.

Common Problems That Are Caused By Hard Water

Most water stains have a white color, but they might also be brown or rust colored. If standing water is allowed to naturally evaporate away, the minerals get left behind, which produces a hazy stain.

There are three main problems that are caused by hard water:

  • Water rings: These can form on surfaces when water is allowed to evaporate from the outside portion of a glass.
  • Limescale: This is left behind when water is boiled away inside of a kettle, hot water heater or heating element.
  • Water spots and stains: These are left behind when water drips or spots are allowed to evaporate.

How to Remove Hard Water Stains From Glass

Since glass is transparent, hard water stains can be especially unsightly on glass surfaces. Fortunately, there are several ways to take care of the problem.

Non-Liquid Cleaner

Many homeowners automatically jump into using toxic chemicals to remove the stain. Before going that route, it’s best to use some special scrubbing techniques beforehand.

Magic Eraser cleaning pads can be very useful. You can also use non-scratching scrubbing sponges to scrub the glass surfaces. All that you have to do is moisten the sponge or pad and scrub the stains.

You should avoid using hard-bristled pads. You don’t want to accidently etch the surface of the glass with a strong abrasive.

In most cases, simple scrubbing works best on small hard water deposits and new stains. If you’re dealing with stains that have had ample time to set in, then you’ll want to move to the next method.

Using Baking Soda

A great natural cleaning solution is baking soda. You can use it for heavy-duty hard water stains. Since baking soda is an alkaline substance, it automatically counteracts mineral deposits. It’s also a biodegradable product, so it’s environmentally safe.

To attack the stain using this method, apply some white vinegar onto the stain and let it sit for about 30 seconds. Immediately apply some baking soda and scrub the stain well. Make sure to rinse thoroughly.

Commercial Paste

Another method that you can use to remove hard water stains from your glass shower and other surfaces involves the use of commercial paste.

A quick trip to the store should yield a number of suitable options. The greatest benefit of using a commercial paste instead of a liquid is that the paste doesn’t leave its own water marks or liquid streaks.

However, a paste can leave behind a foggy haze, but it must be buffed out of the glass. If you want to try another natural option, you can use something as simple as toothpaste.

How to Prevent Hard Water Stains

Prevention is always better than a cure. A great way to prevent the stains from occurring is to correct the pH balance at the source of the problem, which will balance the mineral content within your water. For example, you might consider adding a filter to your home water system.

You can also install or have a professional install a water softener system, which can be very effective at counteracting the effects of hard water. It’s also important to regularly wipe down your glass surfaces.

If hard water is removed immediately, the chance of it drying into a major stain is much less likely. These are some of the most effective ways to remove hard water stains from a glass surface.
