Run the self-cleaning cycle of the oven to cook off any food debris that remains in the interior of the oven. Allow the oven to cool for at least two hours with the door open before beginning the cleaning process.
Scrub the glass surfaces of the oven in a circular motion using a damp, nonabrasive scrubber while applying medium pressure. Sponges covered in nylon netting work well to remove residue without leaving marks.
Wipe the glass surfaces with a paper towel to remove loosened build-up and to reveal areas that may need additional cleaning.
Apply a small amount of a manufacturer-approved glass cooktop cleaner to the areas that are still soiled.
Apply the cleaner to the glass surface in a circular motion until all of the residue comes off.
Polish the glass with paper towels until the surface is clean.
