How to Deep Clean Your Oven

Ovens are the workhorses of the kitchen, but they rarely get the attention they need until smoke starts billowing during a standard bake. A neglected oven doesn't just look bad; it creates uneven heating and leaves a charred, bitter flavor on your food. When done well, a deep clean restores the reflective surfaces of the interior and clears out the carbonized buildup that hampers performance. Deep cleaning isn't about scrubbing until your arms ache; it is about chemistry and patience. By using a simple paste to lift grease and debris, you save yourself hours of mechanical scrubbing. Focus your effort on the door glass and the bottom floor of the unit, as these are the areas where the most intense heat causes spills to fuse onto the metal.

1. Clear Out Before You Start. Remove the oven racks, thermometer, and any loose debris from the bottom of the oven. Use a dry cloth to brush away burnt crumbs or loose black flakes before you start wetting the surfaces.
2. Get the Consistency Right. Combine one-half cup of baking soda with three tablespoons of water in a small bowl. Adjust the ratio until you reach a spreadable consistency similar to toothpaste.
3. Coat Every Surface. Spread the paste over all interior surfaces, including the back, sides, floor, and the inside of the door. Avoid the heating elements and the vents; keep the layer thickest where the grease buildup is heaviest.
4. Let Chemistry Do the Work. Close the oven door and leave the paste to sit for at least twelve hours, or overnight. This allows the mixture to break down the carbon bonds in the burnt-on food.
5. Scrub Out the Loosened Grime. Use a damp, non-abrasive sponge or cloth to wipe out the dried baking soda paste. Rinse your sponge frequently as you pull out the loosened grime.
6. Shine the Glass Door. Spray a small amount of white vinegar over any residual white streaks left by the baking soda. The reaction will create a light foam that you can wipe away for a crystal-clear finish.
