Do not use MS70 on any coins containing copper. For silver/gold it's best used on AU or MS coins when you want to remove surface contamination or light toning.
It is a harsh cleaner IMHO. It works well and I've used it on many silver bullion coins. I would not use it on any coin of significant numismatic value. The statement, "will not affect coins surface or luster" is not true. There will be some affect to both the surface and the luster of the coin though it is usually minor.
Remember this is a cleaner - experiment with low value coins and see if you like the results.
