All these suggestions sound good to rescue your favorite pot. To really shine it up and to clean any residue that's left, use Barkeepers Friend (on the same shelf as Comet, etc) at WalMart. Have used this product for years on my Revere Ware (stainless) and occasionally on my flatware (the knives, especially). Good to use on stainless steel sinks and ceramic cooktops as well. It's my ace in the hole, as the saying goes. Try it.
