Window screens are useful for protecting your home from pests and debris while allowing you to enjoy fresh air. Unfortunately, those made from aluminum mesh will eventually begin to oxidize from exposure to rain or humidity. When this happens, there’s a risk of the oxidation deposits transferring from the screen to the glass, causing unsightly stains. These can be challenging to get off despite your best window cleaning efforts. The following guide helps explain what you can do to keep your windows oxidation-free.

Prevention Methods

If you prefer to keep the screens you have, it’s best to store them away during the winter months. This will limit their exposure to wet weather. Regular window cleaning is also recommended. Having them washed at least twice a year will prevent the oxidation deposits from collecting on the glass.

Removing Stains

If you go several years without a window cleaning, the oxidation will become etched into the glass. This is referred to as screen burn. Typically, you can reduce the appearance of screen burn by scrubbing the window with ammonia and a steel wool-type brush, but it won’t completely remove the stain.

Glass restoration is generally the best option for making the windows look new again. This process requires grinding down the glass surface until the etching is gone.
