Vinyl Tilt-In Windows
My house had replacement vinyl tilt-in replacement windows in it when we bought it (I have no instructions/manual/information sheet on them). It is now difficult to open/raise the windows on nice days. I'm NOT talking about tilting them in to clean them, I'm just talking about raising the window to get some fresh air. I've kept them clean over the years, but is there something I can use to grease/lubricate them to make them easier to open and close? TIA!!
