How can I clean my stainless steel teapot? I have a rather nice stainless steel teapot that I use every day.  I've started to get some black buildup due to using it on a gas range.  What method would work well for restoring my teapot back to its original condition?
There's a cleanser product called Barkeeper's Friend that is great for stuff like this. http://www.barkeepersfriend.com/
