3. Cover the oven in the cleaning paste
Spread your homemade paste all over the interior of your oven. Use your rubber gloves for this if your oven is particularly grimy. If the paste turns a brownish colour, this is normal.
Make sure to cover every part of the oven in the past - including the glass door.
4. Let it sit overnight
Let the baking soda solution to rest on the oven for 12 hours (or overnight). Meanwhile, it might be a good idea to spend this time thoroughly cleaning the racks.
5. Wipe down the oven
After your oven has spent 12 hours (or overnight) soaking in the baking soda solution, take a damp dish cloth and wipe down the interior as much as you can. A spatula can be used to scrape any of the tough, tried-out baking soda in hard-to-reach places.
6. Spray it with vinegar
Put some white vinegar in a spray bottle and spritz it all over the interior of the oven to ensure a sparkling, thorough clean. When vinegar reacts with the baking soda solution, it will start to foam - this is normal!
7. Wipe down the oven one last time
Take a damp cloth and do a final wipe-down, cleaning every nook and cranny to make sure any remaining bits of baking soda residue is gone. Spray extra vinegar to make sure it is 100% clean.
8. Replace the oven racks
Once the interior of your oven is fully cleaned and dry, wipe down the oven racks and put them back inside. Then, hey presto! Your oven will be sparkling clean and ready to be used again.
