    I believe that's to keep people and/or pets from ingesting it. From Wiki:

    "...Denatonium, usually available as denatonium benzoate (under trade names such as BITTERANT-b, BITTER+PLUS, Bitrex or Aversion) and as denatonium saccharide (under trade names such as BITTERANT-s), is the most bitter chemical compound known, with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharide.[2] It was discovered in 1958 during research on local anesthetics by MacFarlan Smith of Edinburgh, Scotland, and registered under the trademark Bitrex.[3] Dilutions of as little as 10 ppm are unbearably bitter to most humans. Denatonium salts are usually colorless and odorless solids but are often traded as solutions. They are used as aversive agents (bitterants) to prevent inappropriate ingestion. Denatonium is used in denatured alcohol,[4] antifreeze, nail biting preventions, respirator mask fit-testing, animal repellents, liquid soaps, and shampoos. It is not known to pose any long-term health risks.."

    I'm not sure really if rinsing in distilled water is another step I want to take. Haven't had any problems so far and I have looked back at my finds from 2013 and they look okay to me. When I take the coin out of the acetone, I blot it with an old t shirt so the acetone doesn't really have time to dry on there. Then they go to a Mineral Oil soak for a few minutes and get blotted again. I am really concerned about preserving my Lincoln's so I hope I'm doing it right!

    I've been rinsing them off with just tap water, then patting good and dry with a shirt too lol!

    So far, it looks like it's working fine!

    Is hydrogen peroxide good for anything other than dug coins? They will be "details" anyway because of the pitting, verdi and dirt. But HP does help make them readable and much more presentable (than seeing the dirt encrustation). Thanks for any insight.

    I picked up a can of "Goof-Off" (100% Xylene) at Walmart for about $3.50 and gave it a trial. It helped a little, but I'm not convinced that it helps that much, yet. Does anybody have any ideas on proper usage of Xylene to dip copper Lincolns and silver Roosevelts?

    Guys there are two posts above this one that need answers.
    So that is what Xylene is! I am familiar with Goof Off and it does stink. My Maint Tech used it to remove paint from cabinet doors and he almost passed out. I got woozy just walking in the kitchen to check on things and had to get him to walk outside!
