Anyone ever use a Ultrasonic cleaner?

Has or does anyone use one on coins? Any luck? MS's or Proofs? What kind of bath did you use?

Only on dug silver that don't have much of a value associated with them.

I still prefer the rock tumbler though....

Electrolysis, yes. Ultrasonic, no.

I think I may have tried a coin or two in the Ultrasonic cleaner when I worked at a jewelry store in the early 1990's. As I recall, it didn't do much at all.

Man, this brings back memories.........the coin shop dowtown in the early 1970"s.... and the owner dropping coins in the ultrasonice cleasner to brighten them up! Agh.....what memories........(you should see thos beauts nowadays, they need another bath!)

Ultrasonic cleaning is abrasive so it shouldn't be used on coins you care about.

Ultrasonic is vibratory. The coin must be suspended so not to allow abraiding. A water and mild soap mix could be used.

Exactly! I did it on dirty gold for an hour and it worked fine. One even was a $3 that went au55. Would of been a NG for sure because it was crusty,, really crusty

Ink erasers do a better job but for those really dirty coins........try brillo.

I use it with M-Pro-7 a water based cleaner, suspend the coins with floss, I also use it with gun parts and it works just fine.

I had one a long time ago.

It buzzed nice.

3000 psi Power Washer and a bench vise work good in conjunction with one another, too .... Be careful not to clamp down on the coin too hard, it could bend it

Glass bead blasting really makes it shine, too.

After that, send it in to AC

- Grade™.... probably get an MS68 D CAM

I tried it on a couple ol worn out Morgans with a lot of crud in the nooks and crannies. I used distilled water and liquid dish soap. The coins came out looking like bleached, bland pathetic pieces of chit. It shud be ok but be careful to use it only on coins made from non-reactive metals like gold.

And it probably IS ok. Ok enough to get them into you know who's holders as gems.

Anyone ever use a Ultrasonic cleaner?
