[QUOTE="wlwhittier, post: 1676950, member: 18320"]Many of the coins I come across are so filthy as to leave soil on fingers, as well as paper surfaces used to back up photos. What solvent properties distilled water may possess are patently insufficient to do any really effective removal of such crud. Denatured Alcohol, lacquer thinner, acetone, naphtha, mineral spirits, methyl ethyl ketone...the list goes on and on of available and effective solvents for short-term soaking of moderately soiled coins...particularly those with low value but high eye-appeal. Simple Green is gonna be my next adventure with one of the worst cases: a Lincoln wheatie otherwise unworthy of a second glance except for the gunk on one side. I also have a couple older British pennies that were sloppily glued into an album at one time, and still bear the remnants of that adhesive caked on the reverse...great experimental material which, even if completely destroyed in the process (not likely) would be a zero loss. The whole subject...the TABOO against cleaning coins, the infinite care one must exercise using the mildest of solvents, the opprobrium attached to the admission of having cleansed a coin: IMO is outrageously overblown and elitist. I am not talking here AT ALL of high value coins...toners, the ancients, etc...[B]nor[/B] about any attempt to [B]'improve appearance in order to deceive'[/B], [B]nor[/B] about scrubbing with abrasive bristles or powders, using aggressive metal cleansers or high or low Ph fluids. Just as you wash any item to remove soil-of-use, I strongly believe many coins shown on these forums would be enhanced by [I]gentle[/I], thoughtful cleaning...just as my penny with the yellow lacquer will be. I'll add to that post upon completion of my labors. I look forward to hearing from all who have an opinion about this subject.[/QUOTE]
