How to clean a gas oven effectively?

To clean a gas oven effectively, start by removing the racks and soaking them in warm, soapy water. Next, mix a paste of baking soda and water and spread it inside the oven, avoiding the heating elements. Let it sit overnight, then wipe it clean with a damp cloth. For tough stains, use a vinegar and water solution or a commercial oven cleaner. Finally, rinse the racks and place them back in the oven.
