It still doesn't matter what kind of pot or pan it is, no stick, aluminum, cast iron, Teflon, or glass, if crud is stuck on the bottom, just add water, put on stove, heat and let it simmer a while. The crud will break loose. Just that simple!
Actually, I remember those days when Teflon was still a new concept in cook ware. After a while the Teflon would begin to peal off the bottom of the pan, and we'd find little specks of it in your fried eggs and stuff. We ate it anyway. I guess it didn't kill me ;) After all, I'm still here, but for the life of me ... da, da, da, uh, um ... well, I can't remember who I am any more! :)
