[QUOTE="desertgem, post: 3018153, member: 15199"][I][/I] Denatonium benzoate and Denatonium saccharide are 2 extremely , but non toxic substances that produce unbelieved bitterness and usually vomiting. Added to many potential harmful things that shouldn't be consumed. Typically in parts per million so it will not cause damage to coins/metal. You can not get many chemicals pure unless you are an educational lab or better. Use it , any change you see was not from it affecting the coin. Acetone is found in the human body in minute mounts from metabolism, and especially higher in certain medical problems. Gasoline is not~ avoid consuming it. China has now perfected odorless shower curtains and other vinyl products, so people who buy such have to look carefully. Not smell. Plant fiber based material such as cloth or paper has a hardness value when dry higher than gold, silver, copper, so I wouldn't use on less than Nickel clad. IMO. Jim[/QUOTE]
