The link worked for me - excellent article, considers the various types of chemistry relating to the cleaning of coins.
General rule: don't clean coins, you will almost certainly ruin the value.
This article is: IF you MUST clean a coin, THEN this is how.
Article does not cover how to clean ancient coins after recovery from ground burial.

Link works now--thanks for posting! Not sure that I agree with everything (which is perhaps the main point...) Quote:

The link works now, thanks!  It's a nice article. There are couple things I'm wondering about. I have thought of trying isopropyl alcohol because it is very good at removing adhesives and the sticky film after someone used Windex to clean plastic but, then I saw this: Quote:
Although certain very pure alcohols can also be used as a post-acetone bath, this type of chemistry is more complicated; so keep it simple with distilled water. I read that isopropyl alcohol can react with certain metals such as aluminum but, I don't know the whole story and it's not really explained.  I was also thinking about trisodium phosphate (TSP) or a "substitute" but, again, that's not spoken of by having a blank section. Quote:Use of 100% high grade acetone is essential; it's stored in metal pint or quart tins in the paint section at the hardware store, not at Walmart or Target. Is there something wrong with the acetone in the metal container in Wal-mart's paint section? In Memory of Crazyb0 12-26-1951 to 7-27-2020

Interesting article, not all of it is correct. Might make a good link to give to people that come on here asking "How do I clean my coins"

I don't agree with the blow dust off with mouth either. Grading companies don't use their breath to blow the coin off before they encapsulate the coins!
