Sometimes in the normal use of an oven, spills can accumulate between the layers of glass on the oven door. This can be an unsightly smear on an otherwise clean oven door. If this happens and your oven is still under warranty, you can call for a service or repair to help remedy the situation. If your oven is not under warranty, learn how to do the job yourself.
Place the sock on the bottle brush or the dowel and pull it all the way down to completely cover the bottle brush or dowel. If using a dowel, attach the sock with several rubber bands to keep it secure.
Spray your sock-covered implement thoroughly with window cleaner until the sock is saturated.
Remove the oven drawer and put it aside.
Lie down on the floor and look up at the bottom of the oven door. Find the holes in the bottom of the oven door, which should be large enough to accommodate either the bottle brush or dowel.
Poke your sock-covered implement up into the holes in the bottom of the oven door, and wipe it back and forth to remove the stains from between the layers of glass.
Repeat with fresh window cleaner on the sock until all of the stains are removed.
Replace the oven drawer.
If you cannot completely remove the stains, consider placing kitchen towels on the oven door handle to hide the stains.
The oven door must be disassembled to clean these stains properly. If you decide that this is necessary for your situation, you should call for a service because reassembling an oven door is quite difficult.
