Regarding getting teflon off... Well, its a sod, it really is, but thats the point. Physical methods are your best bet; sandpaper would be my choice.
Teflon is less chemically resistant than they make it out to be, but still, nothing you want to handle at home will either go for the teflon or any of the binding agents used in the coating.
