To remove burnt-on food or grease stains from your range, use a non-abrasive cleaner or a mixture of baking soda and water. Apply the cleaner or mixture to the stain, let it sit for a few minutes, and then wipe it away with a soft cloth or sponge. For stubborn stains, use a plastic scraper to gently scrape away the stain, being careful not to scratch the surface. Always make sure to rinse the area thoroughly with water and dry it completely.
