The MS70 should do fine with the haze. I've used it on clads before.

@penny yes it is, its also a coin cleaner for lack of a better word. http://www.amazon.com/MS-70-oz-Coin...p/B000YQBZPEIm pretty sure that links it. Not sure if coins would grade or not after it but I have heard that it will change the color of copper coins. |

Only one of those two substances is an inert chemical, and only one of the two does anything about PVC plasticizer outgassing.
MS70 is a cleaning agent. Any coin you use it on is then cleaned, by definition. The manufacturer calls it a "coin cleaner."
So you can figure what my opinion is of it.

Is it more harmful than dipping a Morgan ?

Definitely try acetone FIRST! MS70 would be a last resort IMO. Acetone will not damage the coins but I can't say the same for MS70, so you have nothing to lose with acetone.

No, not even close. MS70 is essentially soap and water, understanding I won't recommend that for a coin either. The Kennedys here need to go into acetone first, to ensure that what Pipewelder is seeing isn't PVC. Beyond that, I suspect any further step will do more harm than good, and if acetone won't remove it, MS70 doesn't stand a chance. |

I have dipped plenty of clad coins and never had one turn brown. First I have heard that one.
But yes, acetone first.

I used acetone on one of the proofs. It cleaned the the milky haze off. Coins still a champagne tone but I can live with that I guess.

Ok I could not resist. I bought some MS70 and used it on a few old circulated Franklin halfs I got in a 90% lot... holy crap that stuff works.. So I tried it on one of the already cleaned but toned Kennedy proofs and MAN what a shine. Look brand new.
It did nothing but improve the look of the coin.

Ill do a before and after on a few in a few days... Several of the proofs have that haze/film that need to come off before they go in an album.

Here is a thread showing before and after on a roll-found JFK proof (clad) and MS70. Acetone did nothing to it. https://goccf.com/t/138854 |
