This will usually allow you to easily wipe the metal clean with a damp paper towel. I son't think I'd do this with pans that have exposed aluminum or copper though. A completely clad stainless steel pan will be unaffected by the amonia, but the crud will come off easily.

Good Call. When we go camping and have camping pots, kettles, etc, we just rinse and wash as best as possible. Then we splash with ammonia and toss into a black heavy duty garbage bag (tightly tied in a knot). Once home, these black greasy cruddy things wash up pretty good. Some stains remain of course but they no longer mark everything they touch.
