How can I clean my oven window? My oven has a convenient window on it.  It is very old and covered in soot.  I tried what many recommendations say and used water and baking soda together, but it did not cut through the grime.  Does anyone know how to get rid of this mess?
Oven cleaner will take that right off. If you're sensitive to nasty harmful fumes you can get the fume free kind. 

Make sure you follow the manufacturer's instructions to the letter, and make sure no kids or pets are around.
