I learned something new from another site. My range had a condensation stain between the glass, a drip mark. Apparently someones husband figured out there were slots under the door where you can get something between the glass and clean off the streaks so you don't have to take things apart. I think someone used a dryer vent cleaner but I had to make do since I don't have one. It worked pretty well with a cloth napkin and vinegar and cake icing spatula, although I may have made some minor scratches but not noticeable. I don't have a line anymore. It looks less cloudy too. I did cut myself so be careful if you try it, maybe wear gloves. I saved a trip from a repair man, although I probably would have lived with it.
