Window Cleaning questions, answered by experts

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.

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.

Clean regularly and inspect seals for wear. Replace damaged parts promptly to maintain effectiveness.

You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.

Access to professional tools ensures streak-free finishes and safety in hard-to-reach areas.
