If you have ever left your stainless steel pots or pans on the stove for too long, you know just how tough those burn marks are to remove. A great trick to removing the burn marks is to cover them completely with baking soda and white vinegar. The solution will foam up as it begins to break down the marks. Let it sit for about a half an hour and attempt to clean with a scouring pad. A second application of the solution may be required.
