How you use and how often you use the oven will determine the frequency of cleaning. Spills and overflows should be cleaned as soon as possible. Seasonal cleaning is recommended or clean when you smell smoke or a greasy odor when the oven is turned on.
Even though baking soda is non-toxic, you will be using it in a small, confined space. Consider wearing protective eyewear to prevent accidental splatters to your eyes. Rubber gloves are also recommended to protect manicures.
Empty the Oven
Remove the racks, in-oven thermometers, and oven liners from the oven. To make cleaning easier, use steam to soften the stuck-on grime.
Leave the racks in the oven and place a two-quart or larger oven-proof bowl or baking dish filled with cool water in the oven. Set the oven temperature to 450°F. and the timer for 30 to 60 minutes. The heavier the grime, the longer the container should remain in the oven.
Turn off the oven and leave the door closed until the oven has cooled completely. The grime will be softened and ready for cleaning.
How to clean an oven rack
Mix a Cleaning Paste
Combine one cup of baking soda and two tablespoons of water in a small bowl to make a thin, spreadable paste. Double the recipe if your oven is large.
Spread the Paste, and Let It Work
Use a sponge or clean paintbrush to spread the paste on the walls, floor, and interior side of the door of the oven. This method is safe to use on both metal and glass oven doors. Do not put the paste on electrical heating elements and gas vents. Close the oven door and allow the paste to work for at least an hour or overnight.
Clean the Oven Racks
While the baking soda is working in the oven, clean the oven racks. Place the racks in an empty sink, bathtub, or heavy-duty plastic garbage bags and spray them with distilled white vinegar. Sprinkle the racks with baking soda. When the foaming stops, add hot water to the sink, tub, or plastic bag until the racks are fully covered, and let them soak for at least one hour or overnight.
Wipe Paste and Reassemble Oven
When the baking soda paste has had time to work, wipe down all of the oven surfaces with a damp sponge or microfiber cloth. If stuck-on food remains, sprinkle a bit of dry baking soda on the sponge to scrub it away.
Mix a rinsing solution by combining 50% water and 50% distilled white vinegar in a bucket. Use a sponge or cloth to wipe away any remaining residue. Remove the racks from the soaking water and wipe away any remaining grime with a sponge. Dry the racks and put them back in the oven.
Additional Tips to Keep an Oven Clean Longer
When possible, cover foods with a lid, foil, or parchment paper when using the oven to prevent splatters.
Do not overfill baking pans to prevent overflows.
Use the oven’s self-cleaning feature regularly.
Wipe up spills as soon as the oven is cool enough to clean safely.
