I use acetone quite often but with a different technique. I take a Q-tip and dip it into the acetone and gently distribute it over the coins surface while easing the residue off the surface. The whole process takes less than a minute and uses very little acetone. Our smaller bottle has been in use for years.
I dumped a Gold coin in Acetone and then sent to NGC, it looked great, better than before and it came back with a decent grade. No details moniker on the slab.
@@mrparrehesian1742 Excellent! There's no issue with using safe methods of 'cleaning' coins. The trouble begins when folks try abrasive and damaging methods!
I never soak the coins instead I use a cotton swabs dipped into the acetone and gently in a circular motion rub the coins. Change to a clean swab as it obsorbs the tape residue
Good demonstration. I personally haven't used acetone...yet. I've used 70% or 91% Isopropyl alcohol for to remove/lift the verdigris of some coins. I soak the coin in a little bottle cap, then use a cotton swab by rolling it to lift the green stuff off. This rarely happens because I try to cherry-pick coins without stuff on them. Thanks for sharing @CAD Roll Hunter.
I have a few coins I might try that on - I have some 1948 and 1949 penies with verdigris, and they're some of the harder to come by varieties. At the moment the entire bust of King George is obscured. I can't make them worse!!
@@CADRollHunter Another tip, for when stuff is still present at crevices and edges of relief/details, I like to use the fine point of a soft green rose thorn to remove it. Key thing is for the thorn to be very tender so it does not scratch coin's surface especially if coin is copper. Copper is most of the time delicate. Good luck.
By the looks of the condition of the desk finish, I'm going to figure, that it won't come out well for the finish on the desk top and you are probably going to find out that you'll have to re-do the entire surface, because of how deep the finish was? That's just my opinion from what I see? And I too! Am sorry for what happened to the desk top surface. And I really love the video of you trying to use the acetone for the tape on the coins, because I have the exact same problem with a few of my coins and it's nice to see what will happen to mine and what I should use on them! Thanks for the videos and good luck with your desk top.
Great information, James. I completely agree with your video. Acetone goes a long way, no need for extended soaking. Also Acetone is my go to for any unknown residue. If Acetone can't remove the issue sometimes I use wax and silicone remover which can be found in an auto parts store or in your local big box store. This especially helps removing the gums found stuck to alot of coins.
Another note with acetone, it acts as a central nervous system depressant. If you’re going to be around it for a while, it might be worth getting a respirator. I got tired of feeling sad after using acetone to clean coins, so I got a respirator with organic vapor cartridges.
With one batch of silver/billon coins I put the coins in the jar first and then poured in enough acetone to cover them, the liquid turned blue. And it was only that batch. I'd done the bathing run as an experiment while reading a book outdoors, but with winter coming, I'm looking at doing this indoors. Just how paranoid should I get about ventilation? I can do this stuff in the garage, but insulation is becoming a greater concern in the waning months of the year than ventilation. The containers I use are 10cl glass jars with enameled steel lids. And since the time requirement for a bath has been ranging from minutes to days on various forums, I bathed most coins on my trial run with a 20min bath and put any coins with any remaining gunk on them back in. Unfortunately, there were still some iron and copper coins that had something on them, but that could be regular corrosion.
I think as long as you have the jars sealed, you're probably fine. Acetone will evaporate quickly, so leaving the lid off will dissipate the liquid into gas and you'll certainly want ventilation for that. Interested to hear how your next batch goes. Keep us updated!!
@@CADRollHunter well, outside again as I type. Bronze and copper Finnish coinage. All five jars immediately had the acetone solution turn blue... The current batch didn't pass the sticky test. I've left the jars in the veranda overnight, see if that does it for 'em. I'm gonna need more jars...
@@CADRollHunter not every jar gets blue solution from the acetone bath, but I'm noticing a slight trend of white residue remaining on some coins in various nooks. Overnight soak got them to pass the sticky test, but getting rid of that residue would require a paper towel. Good thing these were circulating money...
@@CADRollHunter finally got to putting an overnight batch in the garage. The resoak rate is pretty rough with the coppers, but I hope they're better tomorrow. I need to get more jars and work a better disposal strategy for the contaminated acetone during winter. When doing this outside, I soaked paper towels in the used acetone and unfolded them tolet it all evaporate. The paper was left turqoise thanks to the PVC, which I assume is the reason the acetone turned blue in soaks.
@@Tounushi I'd love to see your results. If you're comfortable, can you send me some pics to cadrollhunter@gmail.com? I won't share them with anyone! But I'm really keen to see some before/after!
Yeah I saw that he forgot about the first thing that anyone should try, is a test piece (first) as far as the jewelry goes I would definitely check metal content and check with a jeweler on anything of extreme value? It may possibly do to the jewelry? What it did to the desk top
Very good point - testing it out first would always be a good idea! And I'd also advocate doing some research on whatever solution you're using and expected reactions on the specific alloy. Not all metals would react the same to different chemicals.
It has been said that acetone is not cleaning so much as restoration. If the tape residue is not removed, the residue can destroy the coin with PVC, including the dreaded bronze disease, which is certainly present on at least some of those coins.
Used this same method when I bought a cull Morgan dollar that had paint on it... Came out looking almost BU !! Not an overly valuable date/mint, but I basically got a really nice Morgan for melt. 😂
I have some possibly really good error pennies from the 60s 70s 80s and 90s Penny's I won't send out to be graded because usually the grading cost more than what the coin is worth if anybody's looking for pennies and that error leave me a message
You could probably try soaking in vinegar overnight for steel coins. Just note that if it's plated with anything other than steel, it might not work well at all! And vinegar is an acid, so it's going to affect the coin...

I know that's a technique used by others (e.g., Daniel at CoinHelpU has demonstrated this technique).
Wont the qtip scratch the coin?
@@corners3755 - Yes, according to a U.S. Coin Dealer.
He strips off part of the cotton so the hard compacted ''cotton ball'' isn't as stiff.
Never do that it will scratch the coin and cause damage. Just let them soak it. The acetone will do the work.
Acetone will get rid of most any organic residue. It won't remove verdigris though, in which case you can use Verdicare.
I'll have to look up that product. That might be another video! I have a few good candidates!
I have a couple of colorized silver eagles I was thinking of dipping in acetone to get rid of the decal
That should do the trick for sure!
Seems to have worked rather well. Thanks for the video.
Thanks - I wasn't exactly sure how things would turn out, but I'm pleased with the outcome!

Based on what happened to your desk, I guess a better place to do this stuff is the backyard.
No doubt!!
Have done this on taped and pvc damaged coins for my collection. Definitely agree with all safety tips, and not cleaning coins in general.
Thanks so much for watching!

I'm impressed at how some of those coins came out. Sorry about the desk situation :(
Well, I should have been more careful! But I'll see if I can refinsh the bad spots!
Did a good job, especially on your desk. Ouch.
Yup - that's strong stuff!!

It certainly made quick work of my desk - it works really well, and very quickly!
😂
Wow, that really works!
I wouldn't hesitate to try it again for coins with tape residue. There were a couple better dates in that bunch, too!
Another note with acetone, it acts as a central nervous system depressant. If you’re going to be around it for a while, it might be worth getting a respirator. I got tired of feeling sad after using acetone to clean coins, so I got a respirator with organic vapor cartridges.
Prolonged exposure would certainly not be healthy, that's for sure. Best to take such precautions.
Wow they are beautiful coins. Keep up the good work. I sure do enjoy videos. I am a subscriber to youtube.😊
Thanks, Erwin! I appreciate you watching!
Nice job! Coins look great.
Thanks, Bob!
Great video, I recently got some to use on my proof half dollars I found. A lot of them have paint on them, so it should remove that no problem!
For sure - I hope they turn out great!

Can i use also that acetone in my gold jewelry ?
I believe so, it shouldn't affect the metal at all. But... please don't take my word for it - do a bit of research, just to be sure!
@@CADRollHunter i search it and it can damage gold too like chlorine of the pool can damage gold jewelry

How to clean steel coins

Fun fact: I collect dirty and damaged coins
Those coins have a story to tell!
@CADRollHunter yep! So many of them. I found a "black" loonie. Like is this a 2022 commemorative
How many cats do you have?
Not enough, but too many!
@@CADRollHunter hahaha. I sent you a PM on FB.
