Window Cleaning FAQs, answered by experts

Getting a streak-free shine after cleaning your windows requires both the right cleaning solutions—which can either include warm water and dish soap or warm water and rubbing alcohol—and the right tools—namely, a squeegee and a microfiber cloth. To make your streak-free glass cleaner, combine one gallon of warm water with a few drops of dish soap, and mix. Apply with a sprayer or sponge, and then dry with a squeegee, microfiber cloth, or old black-and-white newspaper pages.

The simplest way to clean stained glass windows is by using warm distilled water and a damp cloth. Distilled water won’t corrode the stained glass or leave residue behind. Avoid using cleaners with alcohol or ammonia. However, you should only clean when necessary. Stained glass windows are fragile, and excessive cleaning could cause fading, weakening of the solder, or other damage.

Professional window cleaners typically use either a white vinegar solution or a commercial hard water stain remover to clean hard water stains on windows. A common vinegar solution for this purpose consists of one cup of white vinegar mixed with a gallon of distilled or bottled water. The pro will spray the mixture and lightly scrub the window with a scrubby pad before cleaning with a standard cleaning solution. Alternatively, they may use a commercially available hard water stain remover and a scrubby pad, followed by a complete cleaning.

The easiest way to remove window decals is to soak the area in hot, soapy water. Let it sit for 15 minutes before scraping it with a plastic scraper or the edge of a credit card. You can also remove window decals with white vinegar, rubbing alcohol, or applying heat from a hairdryer or steam cleaner.

Yes, utilizing green solutions that are safe for both homes and the environment.
