An interesting question - would heavy water (of any sort), be a better cleaner? Its dipole moment is slightly greater but its viscosity is quite a bit higher (perhaps reduced contact and mobility of ions in solution - could make quite the difference). Its density is also slightly greater and the heavier the water the lower its pH (it becomes slightly alkaline)...I reckon it probably would function slightly faster for cleaning, but not all that much.
Would have to do some reading on the actual action of the water and what really limits its ability to clean. Who knows, there might be a better solution to the problem.

I know this is very off topic
For personal reasons I have long had a fascination with that 'other' disaster.
I recently watched a BBC docudrama about the events of April 26 1986 in the Ukraine.
Rarely has a one hour television production brought me to my knees (so to speak).
In brief (as I learned elsewhere)
28 Firefighters died trying to put out a fire the likes of which they had never seen. A pillar of plasma glowing blue red and yellow rising 1000 meters from the ruins of the reactor #4 building.
Over 600 Soviet helicopter pilots perished after flying thousands of flights over the exposed core dumping sand on it to slow down the emissions.
Lastly 2 Soviet Navy divers volunteered to swim beneath the doomed reactor in order to drain off the water the firemen had vainly used on the burning building. This was to avoid a thermal detonation which the physicists predicted would render the entire Ukraine (and more) uninhabitable for centuries. They never returned. Perhaps they wisely choose not to even try.
I will not post the link but google will bring you to Youtube

Ben, to answer your question I think any difference between regular DI water and heavy water would be negligible as far as cleaning is concerned. When I was in college I shared lab space with another guy who was using HW for some type of Iodo-form Kinetics experiment, and the stuff was mondo expensive. When we did the math it was $25 per drop.

You can get a 10 gram bottle of heavy water for $12. I'd have to give some thought as to whether it would be better but I doubt the differences would be noticeable.

Hi, P.P. Have you thought of trying this?  Available in Japan - Not sure about the U.K. (Strange people the Japanese.)  Edited by Topcat7

No idea on your original question PP, a lot of the detectorists are using jade oil at the moment and that seems to do a good job, pretty quick too.

From what I can see jade oil is used for water displacement. Not sure what the purpose would be for cleaning coins.

Sorry pishpash. Australia just defeated England a few minutes ago, in a one day match inside 40 overs, to win a bonus point as well.
Actually, I am a Lancashire supporter. My office used to be almost next door to Old Trafford CRICKET ground.

I just heard on the radio! We are Lancashire supporters also. Husband would have been green with envy about your office.

pp: I worked in the Stretford Council offices on the top floor, on the other side of Talbot Road. I could watch test matches live, and for free, simply by looking out of the window while at work.
On the subject of the thread, I don't like the idea of a solution of chloride ions in direct contact with the coin.
I think I will try an experiment:
drop a bronze coin in a solution of brine, and observe over a period of time.
Got lots of old worn pennies of George V and V1.

One of husband's customers overlooked the ground (one of the Electricity firms), he could never get a meeting at the right time lol.
For the record, the smart water went down the sink.

Check out The Distilled Water Company ,UK http://www.thedistilledwatercompany.com/10 L 24 GBP Also searched difference between distilled and demineralized, DM contains micro organisms and organic compounds , not good for coins ? |

Organic compounds is a very (very) broad term. The organic compounds present in water shouldnt really do any harm - the only ones that would cause special concern are the very reactive and the ionising - the very reactive shouldnt be in the water anyway and the ionising are removed in the dionisation process. There might be some solvent in there, I guess, like acetone.
The only issue here is UV interaction with the organic compounds - can caue some interesting side reactions. But in DI water it wont present any measurable difference.
Also, leaving Distilled water out in a pot will ievitably lead to microorganisms setting up camp. Those organisms are probably going to pump out some organic compounds.
