I have tried a few different products (aerosol cleaners, dawn, ash) to clean my stove door glass over the last 2 or 3 months, retail cleaners are becoming to expensive. So, the other night in basement i happened to see i had some Simple Green and decided to try it. I sprayed my glass and let it sit for about 5 minutes, no dilution. Then I took a nice new razor blade and literally cleaned the glass in less than 10 minutes as the pictures show. I then wipe it a few times and then clean it again with some Windex to make it clear as new. I have tried this little trick a few times now and it seems to work quite well, and it's cheap.
