Successful dip ?

I recently started upgrading my Ike dansco album and came to find out one of them that was a bright white silver coin when I put it in there had grown an ugly skidmark looking stain and a small green spot.I dipped it in EZest for 3 seconds and immediately rinsed it off with water and patted it dry.The stains came off but now it has smoe tiny water spots that may come back to haunt me in the future.What could I have done to avoid getting water spots?

    Give it a bath it in acetone after a quick water flush. Then place in 97% isopropyl alcohol. The pat dry. i use a compressed can of air as well to make sure water is not left on the coin. But I must admit I never dipped a coin before. I start at the acetone to make sure any pvc is removed from my coins I buy raw. Still too many people store in old PVC flips at shows. Good luck.

    What Oney said. The acetone and alcohol baths should stabilize the surface and minimize the spots.

    Regarding the vinyl flips -- why do they still sell those damn things? After the Coinmaster PVC album fiasco in the 70s, I do not why they made them in the first place! They ruin coins, even if they are in there for a short period of time (like the proof coins that turn in PCGS holders because they were submitted in vinyl flips). BAN the things!!! image

    Soap is simpler, easier, and works just as well. Been doing it for years and have never had residual spots.

    Looks like a sucessful dip. Becareful using the "compressed air" as it is not air, but a chemical that evaporates at room temperature. IT might leave residue on the coins.

  • Looks like a nice clean-up on that Ike.

    I had a similiar experience with Ikes in a Dansco album. Local dealer suggested dipping some that had turned black. He said they were ruined anyway so wouldn't hurt. Got an education in dipping. Also got water spots. Hadn't heard about using acetone to "stop" the dip until I read this forum. So I tried soapy water, rinse, acetone, distilled water then used hair dryer to dry. Don't think it made any difference to the spots that I put on when I did my first "experiment".

    Made me afraid of Dansco albums. I'm not clear on long-term storage for coins. I'm keeping them in mylar folds now. Many of them are toning. I end up putting staples all around the fold to try and keep the air out. I was told this was an inexpensive way to store inexpensive coins. Guess I need to investigate air-tites or something like that.

    "then used hair dryer to dry"

    Using a hair dryer is a big mistake, the motor is turned by carbon steel brushes which wear. the tiny particles are shot ut of the dryer right onto the surface of the coin where they immediately start their destruction.

  • Oops, sorry about that previous blank post.

    Thanks, didn't think of that. Had seen others here say that was their technique. I had read that 97% and even denatured alcohol will leave a residue. Seemed distilled water was best to finish with, but didn't think letting it air-dry was that safe for no spots either.
