How to Remove Water Spots from Window Panes

Rotted windows


Do you dream of spotless windows? Even though the glass might be intact, rain stains or marks from building materials can seriously degrade their appearance. How can you remove rain and snow stains without much effort? Read on to find out.

What Causes Window Stains?

Before you start removing water stains, it’s important to understand why they appear. Water stains form when mineral-rich water dries on the glass without being wiped off. As the water evaporates, it leaves behind minerals, creating chalky white deposits on the window surface.

Besides rainwater, other causes of window stains include:

  • Sprinklers spraying water on the windows
  • Gutters allowing water to run down the windows

Some windows come with a factory treatment that prevents water stains. For untreated windows, you can have professionals apply a sealant, carnauba wax, or water repellent to prevent rainwater from accumulating. These treatments cause water to roll off the glass without forming hard water stains.

How to Remove Water Stains from Windows

Before treating your windows with a water stain remover, wash them thoroughly. Here are four methods to clean window stains:

Vinegar and Water
  • Instructions: Mix water and vinegar in a 50/50 solution and spray it on the glass.
  • Apply: Focus on areas with heavy buildup. Leave the solution on for 1-2 minutes.
  • Rinse and Dry: Rinse with water and wipe dry with a paper towel.
  • Instructions: Cut a lemon in half and squeeze out some juice.
  • Apply: Wipe the glass with the lemon half. Citric acid helps dissolve hard water deposits.
  • Finish: Wipe off the juice with a soft cloth or paper towel, then spray with glass cleaner and wipe with newspaper for a streak-free shine.
Baking Soda and Water
  • Instructions: Mix baking soda and water to make a paste.
  • Apply: Use a sponge to rub the paste on the window, focusing on hard water deposits.
  • Rinse and Dry: Rinse thoroughly with water, then use glass cleaner and newspaper to wipe until shiny.
Store-Bought Products
  • Instructions: Purchase a specialty cleaner designed for hard water stains.
  • Apply: Follow the product instructions and wipe the glass dry with paper towels.
