And did you make sure to thoroughly rinse it when you were done?

jfeed Pillar of the Community United States 1259 Posts	Posted 07/29/2025 6:48 pm Thanks again.. Sorry it took so long to get back to you. Had a cardiologist appointment. I used the aluminum foil method with modifications. I hesitate to get deeply into the process because it can really mess up a coin if not real careful. The dip was for only a few seconds, and I immediately soaked in distilled water and then dipped in acetone before going through a total distilled water soak again. Used one of my tee shirts to pat dry. My wife liked that part...I agree with everybody who suggests that this process should not be used unless you are experienced in conservation.

Dearborn Moderator United States 95443 Posts	Posted 07/30/2025 09:10 am great results jfeed! Now I'm even more curious as to your method (I could use that method om my great Grandmother's silver service tea set. Collecting since 1972. Learning from then on "Tell me and I forget.

Quote: before going through a total distilled water soak again. Used one of my tee shirts to pat dry. No! Never pat dry. Acetone will air dry in seconds, just make sure it is fresh acetone to avoid leaving contaminants. A flowing rinse is preferred.

deadmunny Pillar of the Community United States 619 Posts	Posted 07/30/2025 6:46 pm I've never heard of this method but thanks for sharing. I've got some uglies that I could experiment with. Report this Post to the Staff
Dearborn Moderator United States 95443 Posts	Posted 07/30/2025 10:39 pm yep, me too (I have a few silver quarters in my Dansco albums turning brown and I know that they were fine when they went in). All of them are in the last hole nearest the edge where the mylar slides in. Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.
