Window Cleaning FAQs, answered by experts

Yes, WD-40 can remove stickers from glass thanks to its chemical properties that can break down adhesives. Be sure to wear protective gloves when handling WD-40. Spray the window or glass item, and let it sit for 10 minutes before scraping it with a plastic scraper or credit card.

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.

In most cases, you should get your windows cleaned one to two times annually, although you might want to complete this task more often if you live in an area with heavy pollen or heavy rain or snowfall that soils your windows. It’s also a good idea to hire a professional window cleaning service if you’re listing your property, as sparkling windows will make a big difference in terms of curb appeal and, potentially, your home’s value.

Do not mix bleach with vinegar, ammonia, acidic liquids, or other cleaners or detergents as toxic fumes result from the chemical reaction. Mix bleach only with water to avoid dangerous chemical reactions. Even mixed with water to dilute it, bleach can still be harmful to your skin, eyes, and lungs.

Long-handled telescopic brushes are the best way to clean the outside of a house without a pressure washer. There are even special attachments for cleaning the outside of windows. Use a gentle cleaning solution for both the roof and siding to avoid harming the finishes. Be sure to rinse the area thoroughly with a garden hose after scrubbing.
