A Primer on Window Damage – Part III: Maintenance: How To Care For Your Windows

While the specifics of caring for your windows will vary depending on the manufacturer, window type, and the options you chose for your windows, there are a couple of care and maintenance tips that are more or less universal. Here are some tips to keep in mind:

Preventing damage

If your windows came with a protective film, then you will need to remove the film once they’ve been installed; manufacturers recommend the removal within the first 9 months after installation, and on a day when the temperature is above freezing. Care should be taken when removing the film, as you can end up scratching the glass. Also, make sure no flammable materials are on hand when you remove the film, as static may have built up, and peeling off the film can release the static and ignite such materials, resulting in a fire.

Sealants and other, non-manufacturer films should never be applied to the glass; not only will this damage any coatings applied to the surface, but can result in thermal stress, condensation damage, and damage to the glass.

Care should be taken with certain types of cleaning substances. Abrasive cleaners, for example, will damage the surface of the glass. Acidic solutions, such as those used for cleaning masonry or concrete, will damage the glass and the frame.

When wiping down the glass, avoid the use of newspaper, as the ink may run and cause discoloration to the frame.

Cleaning your windows

Before wiping them down, the window glass should be wiped clean of grime and dirt with a soft, dry cloth. For best results, you should clean your windows using a mild soap-and-water solution, a vinegar-and-water solution, or a liquid window cleaner. Avoid cleaning your windows in direct sunlight to prevent glass cleaner residue forming on the glass. Afterwards, use a squeegee or clean cloth to wipe off the cleaning solution.

Window frames and grilles should be cleaned using a soap and water, using a soft rag or brush. Only dry lubricant should ever be applied to moving parts; liquid lubricant tends to attract dirt.
