How to Clean Cloudy Glass Windows

Updated February 21, 2017

The windows in your home are what allow the sunshine to pour in on sunny days. Acting as a portal to the outside world, your windows enable you to watch your children play in the yard or know when company has arrived before the doorbell rings. Even when adorned with decorative curtains and valances, a dirty window with a cloudy haze is not only an eyesore, but it can impair your view and prohibit the sunshine from making an appearance. To clear up this unsightly problem is a cinch with the right materials.

Fill a bucket with distilled water and add enough dish soap to make it sudsy.

Add 3 tbsp of ammonia per gallon of water used.

Dip a clean, lint-free cloth into the solution and wring it out well.

Wash the windows with the solution to remove any hard-water build-up that may be causing the cloudiness.

Use a squeegee to remove the moisture from the window.

Wipe the window with a clean, dry, lint-free cloth to remove any residual moisture.

Apply a thick layer of petroleum jelly to the window with a clean cloth. Allow the petroleum jelly to sit on the window overnight.

Add dish soap into a bucket of distilled water to make it sudsy.

Dip a clean, lint-free cloth into the solution and wring it out well.

Wash away the petroleum jelly with the solution.

Squeegee the window to remove the moisture.

Wipe the window completely dry with a dry, lint-free cloth.


If you suspect a window's cloudiness may be from condensation, consult with a professional window cleaner as to what your options are for cleaning it.
