I dig this community. It’s close and I have a lot of customers in the Seville Community. The windows are a little older and the frames are different. The frames are metal with a painted finish. If you don’t clean the frames the paint oxidizes. If you wipe the same color onto the window. That is the oxidation process deteriorating the window. The heat here in Arizona is brutal to anything sitting in the sun all day. Cleaning your windows every six months or at least once per year is recommended.
