Hi. I live in a 2nd floor apartment in a house that is over 100 yrs old. I have old, really old double hung windows with fixed, non- movable upper sashes. I don't have a ladder, and don't want to use one either, fear of heights.I got a magnetic window cleaner and it works for the lower sash but I can't figure out how to do the upper sash. Any ideas or hints would be appreciated.
