Window Cleaning questions, answered by experts

Costs depend on fabric type, drape size, cleaning method, and whether additional services like pressing or deodorizing are included.

There are a few qualifying questions you can ask a professional window cleaner to help you decide if it’s the right company for you:

  • Does your price include the inside and outside of the windows?

  • Will you clean the tracks, rails, and other internal components?

  • Are you fully insured?

  • How many years of experience do you have?

  • What kind of cleaning products do you use?

  • Do you have any customer references?

  • Do you provide any other services, like exterior power washing?

Suggesting regular dusting and spot cleaning to maintain freshness.

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.

Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.
