1. Empty the oven
Remove your oven racks, pizza stone, oven thermometer, and anything else you have inside the oven. Set aside.

2. Make a baking soda paste
In a small bowl, mix a 1/2 cup of baking soda with a few tablespoons of water. Adjust the ratio of both as needed until you have a spreadable paste. For me this took about 3 tablespoons of water to get the desired spreadable consistency.
3. Coat your oven
Spread the paste all over the interior surfaces of your oven, steering clear of the heating elements. I used gloves for this portion as my oven was pretty grimy. It helped me really get in there and coat the dirtiest nooks and crannies without having to worry about all that grime under my nails. The baking soda will turn a brownish color as you rub it in; it also might be chunkier in some places than others. That is fine! Just try to coat the whole oven to the best of your abilities, paying extra attention to any particularly greasy areas.
4. Let it sit overnight
Allow the baking soda mixture to rest for at least 12 hours, or overnight.
