Yesterday I posted that I could not find a good way to clean/seperate greasy and stuck coins. I have discovered that the best methods were lemon juice and vinegar inside of a cement mixer but the only problem is that once the coins dry, they turn white. I have tried sand and rice in the cement mixer but they both leave a coat over the coin. I need a cheap and fast way to dry them because there are a lot of coins. Any suggestions?

 Welcome to the forum. Read around here there is plenty of topics on cleaning coins. Your method, sounds like one of the worst methods yet that I have heard. Maybe these are ancient coins which might be a little less of a crime since cleaning those is a common practice. Still vinegar and lemon juice are acids and sand is an abrasive. Why not just sell them in lots uncleaned. They sell them that way and people take much less drastic measures. Edited by TNG

These are not rare or valuable coins. They are common US coins that people have thrown in fountains and have been stuck together with grease and gum. They come in the worst imaginable condition and I am just trying to get them in a condition to send them to the bank. |

First I wouldn't suggest cleaning coins! Second I would say the average person looking at a 30 year old coin that has circulated would know that orange is not the correct color.Based on what your using to clean the coins with I'm assuming we are talking copper.

This post seems really bad on the surface so some information provided in the original post should help  Quote:
The business I work for deals with a lot of coins from fountains and other various places that are corroded together or stuck together with gum and grease. The poster is not dealing with ancients or collector coins, just grungy currently-circulating coins that were pulled from fountains. |

Yes, people are jumping the gun here. HE IS CLEANING COINS FROM A FOUNTAIN!
Have you tried laundry detergent or TSP (trisodium phosphate powder)? Maybe even a combo of them in water would work.

I was first to respond and had no idea so in order to save another load in the mixer I threw in my Two Cents before I learned they were just circulated ordinary coins from a fountain. I went and read your other post and I understand they are stuck together. I now suggest... put on some safety glasses and just use a hammer and roll them up.  |

Not sure a coin collector's forum is the best place to ask industrial concerns as we're not commercial chemical experts... well, BadThad is, lol, but most of us here are not, and you have no interest in preserving these coins, only cashing them in. Most of us here cringe at the thought of throwing any coins into a cement mixer and using harsh chemicals on them. There are literally thousands and thousands of fountains around the world, and I'd venture to say most of them have to deal with coins thrown in them, and accumulating therein. Perhaps you should check with various cities or hotels or banks or other companies that maintain fountains? A quick Google search yielded several possible solutions or resources to contact: http://www.newton.dep.anl.gov/askas...hem00308.htmhttp://thestrippodcast.blogspot.com...n-coins.htmlhere is a place that will even take your dirty fountain coins as is and give you cash: http://fountaincoins.com/and another: http://coin-cleaning-service.merschat.com/I'm sure there are lots of other places that can help you. Good luck! |

I'd really like to see what happened with the deisel. Would have to be cheaper than lemonjuice and vinegar, and I suspect you wouldn't see the etched effects. As to drying... idk... I tend to overthing things... Right now I've got the idea of suspending them in a mesh bag and hitting em with a couple of leaf blowers...

OT - I know what this thread is about, but when I see it in list of the active topics, I mis-think that it says Dry Cleaning Coins.   |

I have a few European coins that are dry clean only. Hate that!  |

When I was in Rome some years ago, I visited the Trevi Fountain, of the "Three coins in a Fountain' fame. At the time of the visit, I felt so embarrassed, because I had NO coins!
Idea!
I wrote out an I.O.U. on a scrap of paper, and threw THAT in!
Hope the remains of THAT do not clog up the concrete mixer!

Most are ignoring the fact that it is still possible that some of those coins are not just regular coins. Remember how many times you've come accross an early Lincoln Cent in change? Roll searchers too find some really great coins in those rolls. How they got there could be from the same poeple that throw coins into fountains. Very possibly ruined by now but there is always a chance of a great find in that mess. However, after a cement mixer, Vinegar and Lemon Juice, even those could be now a pile of metal. Once separated, why bother any further attempts. Just take them to a bank and let their machines do the separating. IF, your still on a mission to do further cleaning and drying, give them a bath in Acetone. Or Jewlery cleaner from Walmart. To dry faster just use a hair dryer. I've been wondering. Did you buy or rent a cement mixer for just that purpose? How much did you spend on Lemon Juice and Vinegar? Are these coins you got free from work? Or did you borrow them? With enough time and money you could end up with each coin costing double what it is worth. Check with metal smelters in your area for bulk values too. |
