I was cleaning some circulated dollars with isopropyl. The more tarnished ones developed a blue tint afterwards. Is there a better solution?

You should never clean coins.

Cleaning coins generally reduces their numismatic value. Since these are circulated golden dollars, it probably didn't hurt their value very much.

If you "have to" don't use isopropyl use 100% pure acetone. But as a general rule,never clean a coin it will only lower any possible value. John1  |

Ive used acetone before and it seemed to work good on a Sac coin.
I had a 2000 wounded eagle and it had to be cleaned. It had frosting with dirty rubbed on it.
Then I sent it to ANACS and sold it then someone resubmitted it to PCGS. PCGS gave it the same grade, I could tell it was the same coin from where the frosting was. Sometimes you have to clean some coins.

Well of course, acetone, verdicare, the usual coin friendly chemicals are excluded when you say "never clean a coin."

Try soy sauce for low value coins like them.
Just let it sit for two minutes on each side in a cup, then swirl it.
After that, you can take it out, get a little bit of the soy sauce on your thumb and forefinger, then rub it.

Golden dollars (Sacagawea and presidents) have manganese in their outer layer so that they register as SBA dollars in vending machines. Manganese is a reactive and fickle medal; the Mint knew this after the war time nickels, but chose to ignore that knowledge in favor of big buddy vending lobby. Once a golden dollar is tarnished, it's toast as a numismatic item (unless of course it is a known error or variety). |

Soy sauce helps with the look.

The alcohol doesn't seem to hurt the silver coins or clad but in my defense use only on coins that are just fillers for your album never use on the espensive or better grade coins. Cleaning is really not the thing to do.

Sir, Please consider that no one likes the Presidential dollar coins, so the way to properly clean them is to let them burn in the fiery pits of melting ovens.

I know the rule about cleaning coins. These are circulated and not valuable, so the only reason I am doing this is to remove skin oils. I'd never use anything abrasive or corrosive. I don't ever plan to try to sell them.
So alcohol for silver, gold, and clad coins, and acetone for golden dollars?

If all you're worried about is skin oils, acetone for everything. I advise that step for all raw coins a collector acquires, anyway.
