When you rinse a coin after a dip, do you use hot water or cold water?

Or does it even make a difference? I would think hot water would do a more thorough job and would dry faster but can hot water hurt the surfaces of the coin? I'm against dipping but sometimes a coin needs a quick dip to make it marketable.

    Cold distilled water in two bowls.

    I always used room temp. Plain in 1st bowl and COMPLETELY DISSOLVED baking soda (low solution) in 2nd. Followed by a pat-wrap in absorbent paper under arm to bring to evaporation and complete dry.
    Then swift into 2x2.

    I use distilled water at room temp, in a separate bowl. I have used hot water, since it evaporates faster, but feel more secure using distilled.

    Aren't you affraid of leaving baking soda residue on your coin? I can see the baking soda as a good way to neutalizing the acid but shouldn't there be another rinse to get rid of the baking soda residue?

    Hang on there a moment. You never said what you dipped the coin in. If in an oil based substance, water of any kind will do very little. If dipped in pure Acetone, there should be very little residue and adding any water would be unnecessary. What I mean is the dipping stuff could make a difference. However if you must, then jsut use distilled water at room temperature and blow dry with a hair dryer set on either just air or warm.
    Now what I would do if I were you would be to add a pinch of salt, a spoon of Vinegar, a splash of Basil and a little Miracle whip. Put that on a salad and leave the coins alone.

    Will this now allow a post? Yep I guess so. I tried to edit my dip rinse as I put em backwards. I do the baking soda BEFORE the plain water.

    But....since coins shouldn't ever be dipped.....maybe I don't do it at all.

    Would you like to be dipped in two bowls of cold water? image

    Sorry but you have to have a better reason that marketable...

    Use only hot water. Cold water cannot completely dissolve the dip chemicals, and as a result the coins have a greater chance of changing appearance due to dip contamination.

  • The last time I used cold water it led to a chilling effect of the coin, which in turn led to condensation from my fingers at the edge of the coin. I had to wait for the coin to warm up to be completely satisfied that it was stable.

    Plain water will not completely neutralize an acid based dip no matter what the temp is. You need an alkaline based rinse to do that, either 99% isopropyl acohol or dissolved baking soda. Water is used only as a final rinse.
