The Hard Truth About Water Stains, And How To Remove Them From Your Windows


by Kyle Ray

We’ve all seen it, either on your glass shower door or perhaps your windows. Hard water stains or limescale build-up are those white spots that form on the glass and seem impossible to remove, even with a razor blade!  Calcium and magnesium are what causes water to become “hard”. 

These minerals are dissolved in your home’s water from rocks beneath the earth’s surface. When the water evaporates, it leaves mineral deposits behind. 85 percent of U.S. households have water that’s considered hard, including many people with city water, municipal water treatment plants do not address hard water. 

There seem to be endless products on the market that will help you get rid of those hard water stains along with a few household items hacks you can use as well.  

Water Stains

Here are a few tips that can help you about water stains.

  • A very basic home remedy is to use a spray bottle, white vinegar, and water. Mix half white vinegar and half hot water, spray the hard water, and let sit for a few minutes before wiping down. The acidity of the vinegar helps to combat the alkaline minerals in the hard water deposits. We highly suggest purchasing a “shower squeegee” and get into the habit of removing water drops from the glass after each shower, this will help prevent hard water from forming in the future. This method will typically only work to remove stage 1 hard water, the longer the calcium has been building up the harder it will be to remove. 

  • Now there are more home remedies that you can try but if the build is greater than stage one we recommend purchasing a product called Bio-Clean that you can find on Amazon, we love Amazon. This is a product that we use for minimal stains to more stubborn ones. If the build-up is really bad however we have other products that we use to remove this but its recommended to be used by a professional, using these products the wrong way can cause more harm than good.

Some key takeaways.

For a more permanent solution, we recommend getting a water softener for you home

The issue with using the solutions we mentioned above is that you will end up having to do this again and again. They will keep coming back unless you install a water softener. 

This will take care of most of the issues with hard water build-up on the inside of your home. This won’t however help you with the exterior windows in most cases. 

The hard water forming on your windows is more than likely coming from your sprinkler systems. In order to prevent this from getting worse, you can adjust the sprinkler heads so they are not directly hitting your windows on a regular basis.
