Combine ½ cup (260 g) of baking soda and 2–3 tablespoons (30–44 mL) of water in a small bowl. Wearing gloves, spread the paste onto the burnt areas. Let it sit overnight to loosen the grime.  As you spread the paste around, try to rub it into the particularly bad burnt spots. The mixture should start to turn brown.  Add vinegar to the cleaning paste to make it more effective. As an alternative, spray the vinegar onto the paste just before you scrub it off. The vinegar will react with the baking soda to create more cleaning power. Cut 2 lemons in half and squeeze the juice into a small oven-safe bowl or baking dish. Add the peels and enough water to fill the bowl or dish ⅓ of the way. Put one of the racks in the center of the oven and place the bowl on the rack. Bake it for 30 minutes at 250 °F (121 °C). The vapors from the lemon juice will penetrate through the burned layers, making them easier to remove.  It’s normal for the oven to smoke during this process. Provide ventilation by turning on your oven fan and opening a nearby window. Let the oven cool down and remove the rack before trying to wipe away the spills. These cleaners will probably work better than any other method, so if your oven is really dirty, you may want to try this option. However, these cleaners can be toxic, so you need to make sure they’re fully removed before you cook food in your oven again. Spray the cleaning agent on the burnt areas, and let it soak in for 20-30 minutes.  Wear safety glasses and thick rubber gloves if you use heavy-duty cleaners to prevent the chemicals from splashing in your eyes or absorbing into your skin. Check the package directions to find out how to apply the cleaner and how long to let it soak. Whether you’re using a natural or chemical cleaning product, do your best to keep the cleaner away from the heating elements. When you turn the oven back on, the heating elements can create fumes when burning off the cleaner, which could alter the taste of your food.  For electric ovens, lift up the thick metal wire that forms the bake element and apply the cleaner underneath. If your oven is gas, try not to spray or get cleaner on the gas valve or igniter. If you accidentally get some of the cleaner on the heating element, wipe it away with a cloth dipped in clean water.
