Window Cleaning FAQs, answered by experts

It depends on the surface you’re trying to clean. For example, a mixture of vinegar and water is a good option for a deep cleaning, including removing hard water stains from glass or stainless steel. However, vinegar is too acidic for granite and other types of natural stone, so it’s better to use a combination of baking soda and water on those surfaces.

No, but removing window screens will achieve a deeper clean. If you aren’t sure how to remove your screens, you can still clean them while in your window. You can follow the same cleaning steps, but you may not be able to get into corners or struggle to clean the entire screen if the window is up high.

The best thing to clean windows with is a mixture of white vinegar, warm water, and dish soap. This will remove dirt, pollen, and grime without destroying any tints or protective films on your glass. You can also use a commercial window cleaner, but make sure to choose one that doesn’t have ammonia in it, as this can damage window coverings and frame materials over time.

Professionals remove dust, allergens, and stains while preserving fabric integrity and enhancing the appearance of window treatments.

Yes, professional window cleaners will clean the surface of the glass on both the inside and the outside. They will usually clean the tracks for your windows, check and clean the weatherstripping, and even disassemble parts of your window, if necessary, to clean and lubricate interior components and moving parts.
