Wondering how to clean oven grime without harsh chemicals? Start by cooling it completely. Remove racks and soak them in hot, soapy water. Mix baking soda with water into a paste, spread it inside the oven, and let it sit overnight. The next day, scrub with a damp sponge—grease wipes away easily. For stubborn spots, spray white vinegar and scrub gently. Wipe everything down with a microfiber cloth. Reinstall racks, run a quick self-clean cycle if available, and enjoy your sparkling oven. Regular monthly cleans keep it fresh!
