Acetone is always harmless to coins.

 Use only pure acetone and let it sit for awhile. |

And if you just HAVE to pick after a soak, use a toothpick!

Think of soap as an acid. Never use soap on coins.

I have found coins were there was so much grime on them I couldn't make out the date and/or mint mark, what would be best to do with coins like these? Follow Bad Thad's polarity ladder.  |

Jbuck. Thanks. For that article. Didn't know about xy. I do some metal detecting and some coins could be cleaned ok.

When I was a kid I used to clean dirty coins with a soap called Lava. Sure ruined the coins but they did shine.

Metal detecting is a wholly different game, generally, found coins must be cleaned in some fashion. The Polarity Ladder was written for "normal" coins, not for those those found buried. That said, the first step I'd take on a dirt coin is hot, running tap water and your fingers. I've had good luck with that method on very dirty coins.

I've tumbled thousands of dirty, mostly modern, previously buried coins in a rock tumbler, using a drop or two of liquid soap, aquarium gravel, and H20 to cover, for about a half an hour. These are the only coins that I clean.
Always separate clad from copper when tumbling.

So I was reading about MS70 Everyone says don't use soap. But when I found the ingredients isn't it really just soap?

I have used pure liquid ivory soap sometimes, and only with my bare (and clean) fingers. It really depends on the coin, and if the coins is worth the damage already incurred to it from dirt, corrosion, etc...

To follow my comments on the soap up, this pure nickel coin was from a 1973 Canadian Prestige Double Dollar mint set. The coins in that set were placed in open red felt-like slots (not encapsulated). When I rescued this coin it was covered in a red fluff. A hot water bath, and light touch with liquid ivory soap on my fingertips managed to remove the red fluff and some of the haze affiliated from it. Is it perfect now? No, because a tiny part of the coin's surface has been altered (you can see that in the obverse photo). But, using only my fingertips, no hairlines were imparted upon the coin. PCGS thought it was good enough to pass muster. It is now in a PCGS SP66 holder.

That's what I've been using. And I clean with a soft natural hair paint brush. I try to remove some grime and stay clear of the face or touch only very lightly. Rinse with distilled or filtered water. Then I preserve with mineral oil. I mostly have coins that were already cleaned by someone else and are Low grade anyway. I would never clean a graded coin or proof. I've been practicing on old pennies. 60s.
