Old Coke Bottle

[texmarke]

I purchased this bottle last weekend. I want to get it cleaned up. There is some bottle wear, but there is also a lot of mineral stain that, if cleaned off, might uncover a nice vintage specimen. Can anyone tell me about getting mineral stains off old bottles? This is (I think) a pre "Christmas" coke bottle with the date of patent Nov. 16, 1915. On the very bottom of the side below the date of patent is "CHATT 27". Directly on the other side is the number "10". The Chattanooga "C" is embossed within a circle on the bottom plate along with "GREENSBORO, NC".
