How do I get rid of streaks on my range's oven window?

You can typically clean spills on the outer surfaces of the oven door glass. Sometimes, spills work their way down into the inside of the oven door through top oven door vents. To clean streaks on the inner surfaces of the oven window, pull off the oven door and disassemble it to clean the glass. If you still can't clean off the streaks, consider replacing the door glass.
