PLEASE HELP! My wife and I have a wall oven, and a pile of liquid crap dripped between the panels of the door while she was taking something out of the oven. I was able to remove the oven door without a problem, took it apart, and cleaned all of the panels of glass that made up the door. BUT.... on one of the panels of glass, as soon as the glass dried, the stains re-appeared. The stains look like dried grease, like from a roast or something.
I have tried glass cleaner, vinegar, the wet newspaper trick, etc., but each time, as soon as it dries, the stain re-appears. The glass surface is smooth, it doesn't appear as though it has been scratched or etched by whatever caused the stain.
If anybody out there has any suggestions, I am all ears. My wife is seriously disappointed in my handyman skills at this point. Thanks!
