Tarn-X and similar are just another form of coin dip and has been used to remove tarnish from silver coins for many years. Silver polish has abrasives and should never be used on coins.

In God We Trust.... all others pay in Gold and Silver!
i give some coins a light soapy bath, rinsed thoroughly, but the amount of coins is small. sometimes with an old toothbrush, lightly, very lightly
also i've tested a few coins in an ultrasonic with the rubber basket - ok results. usually just use water, no chemicals. - may do more work with this in the future
the ultimate thing i want to try is a jeweler's steamer. it sprays very hot liquid/steam.
it sounds rough but i've used one before on jewelry and it can be quite effective, if used properly
the main reason is to get "ALL" of the grime out of the crooks & crevices for reasons i'll not disclose at this time
anyone know where a small & affordable unit is, i'd be all ears!

Try it with some low valued coins with and without some detergent and see what kind of results you get.

I believe that you are probably referring to ultrasonic cleaners.
I tried this years ago with some junky circ Morgans using water, a scosch of liquid dish detergent and a small secant of assitone. The coins came out looking, blah, bland, pukey and washed out.
In the old lab/dark back room of a distant and now closed B&M I saw heat remove a DMPL finish very quickly on an "S" Mint Morgan leaving a dead matte surface and nasty grey too. Something to remember.

i understand. proof/pl/dmpl etc would be exempt
there are coin i know that would benefit, but alas until i do it, it is just theory, but one day and one day soon...
the soft toothbrush with dishsoap actually gets me most of the way there, but it is labor intensive
pressured controlled air/steam/water is what i am looking for, or maybe an ultrasonic machine that'll hit about a 7.5 on the richter scale may do the trick
