Window Cleaning questions, answered by experts

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

Because the built-in blinds are encased in glass, they should not get dusty. You might, however, find that your door’s window panes get dirty. If that is the case and you wish to clean your patio door’s glass, first remove any loose debris with a small vacuum or brush. Next, fill a bucket with warm water and some mild dish soap. Dip a clean rag into the bucket and wet the glass on your patio door. Dry the glass with a clean microfiber cloth.

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.

Yes, you can create a solution of dish soap and hot water to create a cleaning solution. You’ll want to mix about one to two drops of dish soap for every 8 ounces of hot water. If you use too much soap, it’ll create too many suds and make it harder to effectively wash away.

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.
