Step 1: Make a paste using baking soda mixed with water.
There’s no set recipe or formula, but the bigger the oven, the more paste you’ll need to make. A good average is half a cup of each ingredient. The main goal is to make sure you get your paste thick enough to spread easily: It shouldn’t be so thick you can’t spread it, or so soupy it drips everywhere.

Step 2: Remove everything from your oven, including the oven racks.
Don’t worry, we’ll get to the oven racks separately below.
Step 3: Apply baking soda mixture.
Put on gloves, and then use a paintbrush to spread a layer of the baking soda mixture over the entire inside of your oven to remove stubborn stains, leaving out the heating element. You can even use this paste on the oven glass if you have a glass oven door too.
Yes, this process will be messy, but your gloves will protect your hands from old grease, soot, and funk. Add extra paste to areas that are really caked with food particles.
Step 4: Allow the baking soda paste to dry overnight.
You should let it sit for at least 12 hours or so. The baking soda will turn brown as it hardens, but that’s okay — it just means it’s doing its job!
Step 5: Wipe away paste.
Use warm water to dampen the paste and wipe it away with reusable paper towels, or you can use a spray bottle filled with vinegar. Vinegar will react with the baking soda and bubble, helping to remove some of the harder, more bound residue.
If you use warm water, wipe away all the gunk you can, and use the silicone scraper or bamboo spatula to help remove anything that’s stuck. Then, you can use the vinegar as a final spray on any stubborn areas.
We love cleaning vinegar because it holds the same properties as distilled white vinegar but is an even stronger cleaning agent. Read more about cleaning vinegar and how to use it here!
Step 6: Wipe away all remaining residue.
Use a microfiber cloth (and multi-surface spray, if needed) to reveal a shiny, clean oven. If the baking soda paste didn’t get the glass door clean enough, you can try using a razor blade to scrape away stubborn debris.
