Cleaning Coins Maybe A Good Tip?

Acetone will dissolve most plastics and those that it does not dissolve, it has the ability to extract other chemicals from the plastic. ALWAYS use glass containers with tight-fitting lids for soaking coins. ALWAYS rinse the glass with a little of the solvent you're working with and discard it.

In general, there are only 3 safe, consumer level solvents you should use on coins:

1) distilled/deionized water
2) acetone
3) xylene

I think I've suggested this before. We really need a separate forum called coin cleaning or cleaning coins.
So many stories, questions, suggestions, etc. are coin cleaning related. However, in a way it could be done if people would suggest to use the TAB for Search on this forum. They could request cleaning coins, Acetone, coin cleaning, distilled water or other similar names. However, one separate place for all such related topics would be easier for new memebers.
The Acetone sold in cans is due to a very complete cleaning of the metal used to make those cans. The process is not just making a metal thing, but a well watched for metal purity so as not to contaminate the Acetone. Acetone can disolve a lot of STUFF so care has to be done to keep it pure. A test should always be done anyway to check for any contaminatios if using on coins. This test also has been explained numerous stimes. Simply place a small amount of Acetone on a clean glass dish and allow to evaporate. Nothing should be left.
Always use glass for dipping of coins in Acetone. And remember you do not have to soak a coin in Acetone. A few minutes will do the same as a few years. I've put coins in Acetone for days and even weeks. Nothing happened after the first few minutes.
Other sources of Acetone, like fingernail polishes should be avoided. They all contain substances for women's nails and a smell to make it usable. Not good for coins though.
Acetone is readily available in almost any place that sells paints. Such as Walmart, Kmart, Target, Menards, Homedepot, Ace hardware and on and on. Usually in quart cans for from $3 to $5 a quart.
Do not use Acetone on or with cardboard, paper, metal, plastic or anything your not sure of. Clean glass is always the best.

Rare items like antiques and coins are worth keeping in the long run. In due time, those collections increases their value as it ages. As a hobbyist and an investor, collecting coins and mining bitcoin is pretty much like investing on a promising business.
