I'll try it on a couple of cheap coins first , but one book suggested making a paste of baking soda and water back in 1976 , it'll clean em alright like ajax would with thosands of tiny scratches . rzage:whistle:
Ketchup, Worcestershire, vinegar, lemon juice - it's all the same stuff (a mild acid) and it all does the same thing. May as well use a dip.
