Recently I have found a few coins that were so encrusted that the only hope I had to get any type of ID of my find was to expose the coins to electrolysis. I genarally use good old salt water for my bath solution. Has anybody had better success with any other types of solutions? i/e baking soda and water, cleaning soda and water, different types of acids or chemicals.... I find the electrolysis method to be a good tool in my arsenal to use from time to time, but I only use it as a last resort. Thanks in advance for your input. Bryan H.
