How can I safely remove plastic that has melted onto a burner?

To safely remove melted plastic from a burner, first turn off the burner and let it cool completely. Then, use a plastic scraper or a razor blade to gently scrape off the melted plastic. You can also try using a mixture of baking soda and water to help loosen the plastic. Be careful not to scratch the burner surface, and always ensure the burner is completely cool before attempting to remove the melted plastic.
