Cover the interior of the bottom of the oven with a fairly substantial amount of baking soda; enough to fully cover it. Use a spray bottle to spray vinegar on top of the baking soda (this will fizz up, making an awesome oven volcano). Spray vinegar on the sides of the oven, the inside of the door, and anywhere else. Let it sit for a few hours, overnight if you can. Use a damp sponge or damp clean rag to wipe everything down, rinsing and rewetting frequently. Have a scrub brush on hand for any stubborn spots.posted by ambrosia at 9:38 AM on June 23, 2013 [1 favorite]
