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.

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?

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.
But....since coins shouldn't ever be dipped.....maybe I don't do it at all.
Sorry but you have to have a better reason that marketable...

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.
