Ultrasonic Cleaning

I dont use chemicals just plain and simple distilled waterin the ultrasonic cleaner, then they go into olive oil and finaly will be cleaned off with a soft toothbrush :smile All this can take about a year, the ultrasonic gets rid of a lot of the hard baked on dirt then the rest is up to time LOL If you can tell me a better way to do it then please do, other wise you are left holding a lump of something that resembles dirt LOL

Ho ho ho - blasting it with waves of energy in order to carve the dirt off the surface can't be that bad!

:kewl:

ROFL

 

So oh great genius tell me how to remove the grime without cleaning!! LOL you cant can you


:kewl:

 

What ultra sonic machine work better than others and why?

 

ROFL - its so much easier to wash your hands after eating! :kewl:

Then the coins won't be destroyed with grime! Ha ha hah hah

 

DeOrc:
I agree with your method, this is one of the only ways to 'curate' the coins that are found metal detecting.

 

Nothing beats leaving well enough alone though. Any cleaning with any brush will leave lines detectible by any grading services today and flag the coin as cleaned or harshly cleaned. Doing this is similar to taking a 500 year old table and sanding it down and then painting it with Walmart paint spray cans. Nice dark green of course.
OLIVE OIL? Not really smart either. Olive Oils are produced slightly different by different manufacturers and thererfore none are exactly the same. Some contain acids, others contain slight contaminates, many contain a variety of fats of different types. READ THE LABLES. Such products left on coins will do as much good for the coins as a fingerprint left by an auto mechanic after chaging someones oil.
Always note that removal of anything on a coin may now be part of the coin due to chemical compouding or just reactions. Unless you know what you are doing it is always best to leave old items of any kind alone.

 

Please tell me then how on earth anyone would know what type of coin they have if they cant see any detail or even the coin itself? All this you must not clean is fine for the majority of coins but something that has been interd in the earth for a few centuries LOL gimme a break Again I will ask someone here to tell me what to do with heavely encrusted coins that is not classed as cleaning LOL and non of you can :hail: You can use a dental pick of course but allways run the risk of scoring the surface of the coin :hug:


:kewl:

 

Are you kiding me? Come on! There is not one anicient coin in the entire world that has not been cleaned! (with the exception of "uncleaned" lots)

 

Are you kiding me? Come on! Choose, a Thick corrosion and dirtcovered coin where no trace of detail is visible, or a more valuable cleaned coin.

 

basically true. However, removal of heavy crusted material from very old coins that would otherwise not be readable as to even what they are would be a logical solution. The problem always comes from the many individuals that assume that cleaning of these ancient coins makes it the thing to do with all coins. Naturally the very careful removal of contaminates on excessively older coins or items is usually necessary to actually help preserve such items as anyone in a museum can testify. Again, the problem is with the numerous individuals that just clean every coin to make them pretty.

 

So now you are going back on what you said previously LOL I was quite clearly talking about Ancient Hevely encrusted coins not modern or even relativly new (Few hundred years old)

Now soaking in olive oil is a widely and long known method of removing encrustation from coins yet you knock it!! and compare it with sanding down a 500 year old table LOL

 

De Orc,

Most of the people responding to this probably do not get uncleaned ancient coins. Do what you do, on any of the forums I have visited that deal in this type of collecting, your suggestions are the same they have.

I personally like to clean the heavily enctrusted coin with electrololis. I have have a recitifier, I set it to 12 volts and let that coin fry! I only use it with super heavily encrusted worn, already corroded coins that have no value what so ever. If you use it on nice coins or proofs, they become totaly ruined. I had a proof silver round that I used for an anode, it took away the mirror and gave it a really neat matte surface. This happens becuase metal leaves the anode in electrolosis.

 

Yeah, with very unclear coins...good idea to clean !
