6. Wipe out the oven
After 12 hours or overnight, take a damp dish cloth and wipe out as much of the dried baking soda paste as you can. Use a plastic or silicone spatula to help scrape off the paste as needed. I found that the damp cloth was enough for me, but a spatula might come in handy in those hard-to-reach places.
7. Spray a little vinegar
Put a little vinegar in a spray bottle and spritz everywhere you still see baking soda residue in your oven. The vinegar will react with the baking soda and gently foam.
8. Do a final wipe down
Take your damp cloth and wipe out the remaining foamy vinegar-baking-soda mixture. Repeat until all the baking soda residue is gone. Add more water or vinegar as needed while wiping to really get the oven clean and shiny.
9. Replace your oven racks
Replace the oven racks and anything else you keep in your oven, and you’re done!
