I recently scorched the bottom of my stainless steal wok. Since I hang my pans in plain view it really demanded I do something about it. Not amount of regular scrubbing would remove the scorching. I decided to tackle the job this afternoon and now it hangs on its hook, looking bright and shiny.
The process was easy and took about 20 minutes total because I repeated it twice.
Place your pot on a burner with enough water to cover the scorched bottom of the pan. Add 1 cup of vinegar and bring it to a boil.
Remove the pan from the burner after its been brought to a full boil, and add 2 tbsps of baking soda. It will fizz so be prepared for that.
Drain the pan and scour as you normally would. Add a little bit of extra baking soda to the pan if you need to.
Mine was pretty scorched and I repeated the process to remove the last 2 inch round faded scorch mark.
Twenty minutes from start to finish, with a stop to check my mail, and get a cold drink, and I was done.
