I have a customer that recently had some new Pella windows and doors installed. She said they told her that the glass has a coating on them and they will never need to be cleaned. The windows only have a little silicone on them from where the film on the glass was removed. I plan on just using a magic eraser to remove the silicone along the edges of each pane. I don’t want to use any razor blades.
Anyone have experience with cleaning these windows?
Thanks for the help!
