"Rudy and his team were great! Quoted me price, some windows required additional work but kept the agreed upon price. Rudy and the team arrived right on time and finished exactly when they estimated. Very nice and respectful crew, always important with kids in the house. Windows look like new! Highly recommend!"

Window Cleaning questions, answered by experts

Yes, pros are equipped to clean various glass types, including stained glass and skylights.

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.

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.

Finding a quality professional window cleaning service is much like finding any other vetted home pro: You should ask friends and family members who you trust for recommendations for window washers in your area and check online ratings. Reading a company’s reviews will give you a lot of insight into the service you can expect. Then, check their credentials and contact them to get a quote. Be sure to ask questions about their process and the products they use to get your windows to shine.

You can use hot, soapy water, white vinegar, rubbing alcohol, window cleaner, nail polish remover, WD-40, and cooking oil to remove glass labels. You can also apply heat with a hair dryer or steam cleaner. Use a plastic scraper or credit card to remove the adhesive, as a razor blade can permanently scratch your glass.
