food particles every time the oven heats up.
When you cook fatty or greasy foods, tiny droplets of grease become airborne. Some of these particles enter the gaps between the glass panes and settle there. Since you cannot wipe this internal surface during routine cleaning, a cloudy, amber film gradually forms over months or years.
This is a normal aspect of most oven doors from leading brands such as GE, Whirlpool, Samsung, and Bosch. It is not a manufacturing defect or poor maintenance—it’s simply how the door’s ventilation system works.
