I saw this on CU and was laughing too hard. Someone was asking how to clean coins and there were all sort of bizzare answers. this member decided to be a LITTLE sarcastic.... You sound like you want to clean some coins. I've experimented with several different things and although many say Acetone because it won't disolved the coin. I've tried comercial grade Acetone, like what you buy at Walmart and it really does very little to a coin. I've tried kitchen soap, hair shampoo, gasoline, paint thinner, battery acid and lots of other fluids. One of the best to clean silver coins is actually fabric softener with a little table salt mixed in. Little soaking and then just rince with water. There is a Silver Polish on the market that has minute amounts of Silver in it so that it makes silver coins really look new. Battery acid usually only works well on copper coins because it's not for melting Silver but will react with the copper coins to form coppersulfate. Oh yeah, the coins will be gone, not just cleaned. Oddly enough if you mix Acetone, gasoline, paint thinner and fuel oil, put it all in a large metal container with thick walls, add your coins to the solutions, then light the whole thing you'll notice after the flame goes out your coins will be well toned. However, many collectors call this artificial toning and that is not well accepted. I once left some coins in a pair of jeans that went through a few wash machine cycles and came out really new looking but a little banged up with scratches. Reallistically, don't clean coins. If as others have said you have some kind of plastic stuck to the coins, then the Acetone is what you want. *** WATCH OUT FOR THOSE EYEBROWS **** POOF !!!!!!  Edited by grovey 06/20/2005 5:42 pm

I had a customer show me a cent he had soaked in Coke to try to get some gunk off. It didn't look too bad, luckily he didn't leave it in there very long. Anyone else remember the grade school experiment where you put a tooth in a bottle of Coke and watched it for a few weeks to see what happened? Eeugh...  Rachel [:p]

I have read a few dozen internet sites on cleaning coins and some are beauts
-Cook in soap use a nailbrush to clean then wash in water and wipe dry -Put in alu foil put baking soda on close foil and drop in boiling water -Use cola, ketchup -Use toothpaste for non smokers the other is too abrasive -Use citric , acetic, sulfuric, phosporic, nitric acid -Brush with a copper brush in concentric circles -Brush heavily with an apple cut in two -Put inside a cut potatoe and bake -Use Cellit Bang -Spit on the coin and wrap in alufoil -electrolyse -ultrasonics in urea and phosporic and blast with woodpulp to dry -use silverpolish
Now some things may actually work - use a camel bruh with 10 inch long hairs - Acetone , ethylalcohol, propanol, Methylethylketone, thinner - peroxide - put coin in deepfreeze
About the only thing that will damage gold on a chemical basis is nitric acid which will bleach the copper to light yellow Gold dips may do the same and of course mercury and aqua regia Anything mechanical risks to damage gold

HF is for cleaning windows or if you are an artist for etching glass But since glass is melted sand indeed it looks like an omission

Well actually I left out the finest sanding paper people use to take the shine of varnish of a door before varnishing it again However somebody reported this leaves like tramlines on the coin Strange

Wet and Dry paper ain't it? Why not dip the coin in sand and sealer too?
