How to clean between glass of oven window
Here is a tutorial for that https://www.hometalk.com/755659/how-to-clean-between-oven-glass
Most stove doors should have a screw that holds the 2 pieces together. Just remove the screw and put the glass in a dishwasher or wash by hand.
My Whirlpool booklet says to pull the door off and clean the glass per the above video and I did just use vinegar and dawn. Looks brand new.
You have to disassemble the oven door. Take your time and have help! .
My Whirlpool just pulls right off and no need to disassemble it to clean. Check your booklet. Open door to first angle and then pull up. Boda boom.
