[QUOTE="Brett_in_Sacto, post: 2423674, member: 71510"]As a reminder - MS70 is not a "dip" it is a mild agent (diluted caustic soda) that is designed to release whatever crud is sticking to the coin by making it more soluble. It's meant to be used as a gunk remover. And I suggest doing it sparingly. I still think dipping the coins ruins them, and it can be detected by the grading companies pretty easily. Excessive use of it will in fact get you a "details" grade and ruin the coin. I experimented on several AU/MS Peace Dollars I sent in last year and had some that were just beyond help without a bit of cleaning. Out of the 7 I used MS70 on, 6 came back with details grades (which they would have anyways - since they all had foreign debris on them). The only one that passed was an MS62 - and I only used it to remove one small spot of gunk. So if you are just cleaning up your coins to look nice in the album - so be it - at least for the 90% silver coins, you should be ok - but it's not a dip. Instructions say to use a q-tip (cotton top for sure). Douse the affected area with the q-tip, let it sit for a minute and wipe it off. Then rinse the coin - I recommend cold distilled water, and don't rub it whatever you do![/QUOTE]
