I cleaned a residential today that the home had recently been sealed with an oil (I think) based sealer. It sprayed onto the screens and wouldn’t come off. It really mars the view out the basement windows. I tried spraying the screens with straight water. Does anyone know of a chemical that would cut the oil so that I can get these screens clean?
If the screens are aluminum you can try Oil-Flo. If they are nylon or fiberglass they will have to be rescreened.
