How can I effectively remove baked-on carbon from my oven?

To effectively remove baked-on carbon from your oven, you can try using a mixture of baking soda and water to create a paste. Apply the paste to the affected areas and let it sit for a few hours or overnight. Then, scrub the carbon off with a non-abrasive sponge or scrub brush. You can also use a commercial oven cleaner following the manufacturer's instructions for best results.
