Vinegar and salt if the worst procedure. What happens when an acid a added to a cent. The surface goes away leaving the pink color that makes it so obvious that the surface was altered. Best to stick with mineral oil on circulated coins to remove the gunk from devices and touch up with a green thorn. Mineral oil will not remove carbon spots, green spots on color, finger prints and never to be used on BU or proof coins. Just circulated coins that have grime on the devices. The other things I mentioned about that it will not remove should never be attempted to remove as what ever you use, may alter the surface and the value drops drastically after the coin as been deemed cleaned. (Can be reduced as much as two grades. So if you don't know what you are doing, never attempt to clean/dip a valuable coin. It is not worse the loss when the coin is ruined.

Woah! Is that even the same coin?! Nice work and find. Also has a retained lamination on the obverse

Do a search on ebay for this program. I've picked up copies of it for less the $25. I have a continual search for these there and I snag them when they are less than that. You just have to be patient till the right deal comes along. Don't get the updated 5.5. You have to have the full program instead of this to add to it. I couldn't see no difference by adding this program. So it is a waste of money for my uses.
