How to Remove Hard Water Stains From Your Glass Shower Doors

Hard water stains might seem as if they’re impossible to remove but you can win the cleaning battle. Hard water is water that contains too many minerals, and those minerals leave spots on your kitchen and bathroom surfaces. If the shower door is seriously stained, CHC Glass and Mirror might have to replace it. First, try to remove the stains using natural cleaning products that beautify your bathroom and protect your family. Here’s how to remove hard water stains from your shower doors.

Grab a Bucket

Put on a pair of rubber gloves. You still want to protect your hands even though you’re using natural cleaning products. Grab a clean bucket and a jug of white vinegar. Start with a diluted mixture of vinegar and water and if that doesn’t work, you can apply straight vinegar directly to the hard water stains.

Mix it Up

Depending on the size of your shower door and whether you are cleaning more than one glass shower door, pour equal amounts of vinegar and water into the bucket and mix them thoroughly. Usually, one cup of white vinegar and one cup of water will suffice, but you can mix more for really dirty doors.

Apply the Mixture

Using a sponge, apply the mixture to the shower door coating it thoroughly from top to bottom. Make sure you get plenty of vinegar and water on the door, especially where the stains are thicker along the bottom of the door. Make sure the entire door is covered with the vinegar and water mixture.


Set a timer for at least five minutes. You may have to wait longer for thick layers of stubborn stains. White vinegar is an organic acid that will gently eat away at the hard water stains without damaging the shower door glass. It can also clear hard water deposits from faucets to restore water pressure.


Rinse away the hard water deposits with hot water after the time has expired. If you still have hard water stains on your glass shower door, retreat the door and allow the vinegar mixture to sit longer. You can let it sit all night if necessary. The white vinegar/water mixture will also remove soap scum.

Bonus Tip

To remove hard water and soap scum stains from the glass shower door’s metal frame, grab some lemon or citrus oil. Pour a small amount of the oil on a soft cloth and rub the metal frame gently to remove the stains. Do this until the stains are gone and the metal frame has a gorgeous shine.
