Pinner says "Ok, I just tried this and it seriously did work. I did it twice on a burner that's had scorch marks for a year or more and they're gone! For anyone as OCD about cleaning as I am, this is a must! I would be prepared to do it at least twice, more if you've got bad burns. This really works!!!"
Keep this in mind if you start seeing lots of spiders around your place. Natural spider killer or preventer... take one cup of vingar, one cup of pepper, a teaspoon of oil and liquid soap. Put it into a spray bottle and spray along the outside of your outside door and along windows; refresh after it rains.
