How to Remove Water Spots from Window

Do you long for spotless windows? The glass might be pristine on the interior, but the rain and snow have left hard water spots on the exterior. Fortunately, you can learn how to remove hard water spots without too much difficulty. Just follow these tips from Glass Doctor®, and your windows will shine day and night!

What Causes Water Spots on Windows?

Before you learn how to remove hard water spots, consider why they have developed in the first place. Water spots form when mineral-laden water is left to dry rather than being wiped off the glass. As the water evaporates, minerals are left behind.

While rainwater can cause spots to form on windows, other causes are more likely to blame. Is a water sprinkler spraying the windows? Are your gutters leaking rain from the roof onto the glass? Address these problems, and you might just put a stop to water spots.

Some windows come with factory-applied treatments to help prevent water spots. If yours lack this feature, you can apply a glass sealant, carnauba paste wax, or rain repellent product to the windows. These treatments allow rain water to roll off the glass instead of beading up on the surface, reducing the formation of hard water spots.

Removing Water Spots from Windows

Of course, before you treat your windows with a product to prevent water spots, you need to clean them first. Here are four methods for removing water spots from windows:

  • Vinegar and water: Spray the glass with a solution of equal parts water and white distilled vinegar. Be sure to thoroughly saturate the areas with the most prominent buildup. Allow the solution to sit for a minute or two, re-spraying the glass as it dries. Saturate a small, rough towel with the vinegar and water solution, and scrub the glass with the towel. Dry the window with a soft cloth or paper towel, and if you still see water spots left behind, repeat the whole process.
  • Lemon: Slice a lemon in half and rub it on the glass with a fair amount of pressure. The natural acidity of the lemon removes hard water stains with ease. Mop up the lemon juice left behind with a soft cloth or paper towel. Finish with a spray of glass cleaner, and wipe it away with newspaper for a streak-free shine.
  • Baking soda and water: Create a paste made with baking soda and a small amount of water. Apply the paste to a cloth and scrub the window vigorously to allow the abrasive granules of baking soda to remove the hard water spots. Thoroughly rinse the glass with water, and then use traditional glass cleaner and a newspaper to remove all residue and streaks from the window.
  • Store-bought cleaning products: Commercial cleaners are available with the specific purpose of removing water spots. For the best results, follow the directions printed on the label of the product you choose. Some products aren’t specifically made to clean windows, so they may leave streaks. To avoid this, finish the treatment with a spray of glass cleaner and wipe with a newspaper.
