It looks to me that a lot of modern Australian coins have there fair share of oils & grease type of soiling build up on them. Nothing new in that statement!
In the past week my adult son sat on our front car seat and left a large, thick mass of tar on it. Scraped as much as I could of the tar off the seat and then poured lighter fluid over the rest and very easily removed the rest of it totally. No smell or anything left. It was just, as it was, before the tar accident.
Has anybody used lighter fluid or shell-lite (same thing) to clean coins? Does it work as a coin cleaner?
Does it do anything to the luster of the coin etc
Lighter fluid or shell-lite totally evaporates leaving nothing no smell, no nothing. Some people will already know about this part of lighter fluid.

I would not recommend it myself. Most lighter fluids, if your referring to the kind used in wick type lighters, is a petroleum distillate called Naptha or Paraffinic Naphtha . It can also be made from coal or tar.
Acetone will remove most organic materials from coins if given enough time. Some forms of naphtha may be carcinogenic, and some products sold as naphtha contain some impurities which may also have harmful properties of their own.

"Goo" on coins can be made of all sorts of different stuff, and some solvents are better at removing certain kinds of contaminants than others. The "polarity" of the solvent has a lot to do with what it can and can't remove. There is a polarity chain of commonly used solvents, running from "most polar" to "least polar":
- water
- ethanol / methylated spirits
- acetone
- xylene
- hexane / petrol / other alkanes
Lighter fluid is more or less similar to hexane in this list. It's very good at removing "non-polar" goo - such as tar. It's not so good at removing polar stuff - like, say, PVC residue.
Acetone is the recommended general-purpose solvent becasue it's "in-between" on the chain: reasonably good at getting rid of both polar and non-polar stuff.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

Wasn't that Gerald Ford? I never read that in any of TJs writings.

Wasn't that Gerald Ford? I never read that in any of TJs writings. Actually Jefferson has been loosely accredited with saying this although there are no known examples in his writings. It's earliest known appearance in print was in 1952. Paul Harvey, Remember These Things, Chicago, Heritage Foundation, page 57. The earliest known appearance in print attributed to Jefferson was in 2005. Robert G. Moscatelli, The Quote Manual Bloomington, Ind, AuthorHouse, 2005, page 193. It was copyrighted in 1957 by the General Features Corporation, as part of a syndicated newspaper feature called "Today's Chuckle." It later became a popular saying among Republican politicians. Governor Harold W. Handley of Indiana used it in his annual message to the Indiana General Assembly in 1961. Barry Goldwater was quoted using it in his 1964 run for president, and Gerald Ford is on record using it in an address to a joint session of Congress on August 12, 1974. It was attributed to Ford as early as 1954, however, and Ford's assistant, Robert Hartmann, said that Ford claimed to have heard the quotation "early in his political career" from Harvard McClain at the Economic Club of Chicago.

Lighter fluid is awesome! It has even been used to shows up watermarks on little bits of very old paper for more years than we want to know about. It totally disappears from the paper. Totally evaporates and after more time than I am old it has not damaged a single piece of very old paper!
Grease on your wife flash dress from the tow ball on the back of the car etc and lighter fluid is your man!

Tim. I've used lighter fluid on copper and silver. Copper can be tricky but if not too long of a soak, it should be fine. Silver works great.

Original is best. Leave it alone.Once you start rooting around with chemicals to try and make a coin look better you just cause more damage.
