Got a question for you Window Cleaners out there... Is there any substance or clever way known in removing what seems to be some kind of Acid released from insects which stains small brown/yellow type spots on the frame. Custys do not seem to complain about this. i make sure all my frame are wiped clean and the custys are happy with this.. just wondered if anyone knew of a way???...
