An old-fashioned, reliable way to clean an oven uses just baking soda, water, and a bit of vinegar—no harsh chemicals needed.
You make a thick paste from baking soda and water, then spread it all over the inside of the oven (avoiding heating elements). Let it sit for several hours or overnight so it can loosen the grease. After that, you wipe it out with a damp cloth or sponge.
For the stubborn bits, a spray of vinegar helps. It reacts with any leftover baking soda, fizzing slightly and helping lift baked-on residue so it’s easier to scrub away.
Finish by wiping everything down with clean water so no residue is left behind, then let the oven air dry.
If you want, I can also give you a faster “same-day” version or a method for a really badly burnt oven.
