So has anyone else ever had an issue with the glass on their englander getting perminantly hazy? It's not real bad but there is an area where the glass is somewhat cloudy. I whip it down is it is crystal clear until it dries and then it is hazy again. I've tried vinegar, windex. You name it. I have a feeling it is perminant. Could i have overfired the stove or something? Maybe the wife used a bad cleaner which I haven't asked?? Any thoughts?
