I bought one of the Revolution era metal canteens and got the stainless steel version so as to not have to worry with rust, leaking, etc. The problem is that it is as shiny as a '57 Cadillac bumper. I tried using both phosphoric acid and oven cleaner to try and knock down the shine. Neither had any affect. Is there a way of chemically dulling the shine of this thing?
Incidentally, to anyone contemplating buying one of these, they are available in two shapes, kidney shaped and half moon. I bought the later, since it would have more capacity, but quickly discovered that the corners will poke into your side rather uncomfortably at times.
