Has anyone ever dipped, dabbed, dare I say "cleaned" early mint state Jefferson nickels?

I have several that are MS, but some look like they've got some.....funk.....of some kind on the surface and I'm wondering if I should try an acetone swish, or something.

Does anyone have experience with dipping nickels? I'm curious if the metal's composition suggest it's best to leave as is, or if nickel actually cleans up well. Not rare, high end coins we're talking here, but I don't want to ruin them either.

nickel dips just fine

I mentioned this yesterday . . .on Warnicks MS70 can really headlight a coin. I like to use MS70 before I try a dip . . . basically using the 'less is more' philosophy.

But a dip works too. You have to determine what is causing the discoloration/haze/etc. Some coins react to a dip phenomenally well . . others (55 dark planchets for example) don't.

Practice with a few mint state cheaper coins . . . . just to be sure.

Mint set nickels from the old four ply years ('59 to '84) should probably be stabilized in acetone. Most
of these are fine so far without it but these apparently get a little exposure to PVC and some dates have
darkened or gotten splotchy. I've never had one that was rinsed go bad but they may yet. This seems to
affect some dates far more than others.
