I wish we could have gotten a gas stove top and oven but it was going to be too expensive to pipe in the gas so the glass top works just fine. Those of you that have one, don't you just hate that cooked and caked on mess it leaves? Cleaners just don't seem to cut it. My mother showed me this trick and I'm sold!
Clean it the best you can with whatever cleaner you usually use.
Sprinkle baking soda all over.
Soak a clean cotton rag with hot water and rub in circles and back & forth to remove those cooked on stains.
Wash out the rag and ring dry. Wipe the stove top clean. You may have to do this a few times.
Now clean with your normal cleaner again to shine.
Yes, I know I need to do it again and rub more in those areas :) but it's better than what it was.
