You can clean your oven door in 5 minutes with something you probably already have – baking soda!
I've learned so many kitchen cleaning tricks since starting a cooking channel, and this has to be my favorite. All you have to do is sprinkle baking soda on the oven door, use a wet sponge to turn it into a paste, and wait 5 minutes. There's no need for vinegar or soap.
The stains on your oven door are made from polymerized oils – basically the same thing that seasons a cast iron pan, but unwanted in this situation. Baking soda is more atomically "sticky" with the polymers than glass, so during the 5-minute soak it breaks that bond down which is why it's so easy to scrub. For any stubborn stains, you can add more baking soda which acts like a mild abrasive.
If baking soda fails you, you can always use a glass cleaning blade/scraper (it's like a razor blade on a handle) but baking soda is easiest.
