What is your favorite, tried and true method of stabilizing a coin after a dip?

MadMonk

Just curious how many, and which, methods are used.

Baking soda mixed with water.

99% isopropyl alcohol.

Rinse in distilled water, then twice in the ultrasonic cleaner in pure distilled water, changing between baths, then a pat dry with a clean diaper and air dry for a week on my table.

I first rinse in running water, then soak for a moment in baking soda water, then rinse in running water again and soak/rinse in acetone.

once in alcohol, once in distilled water and then another different bowl of distilled water, a first dip in acetone and then another rinse in acetone. it sounds lengthy but seems to be working.

BTW, I've used a three stage dip of acetone. I never dipped a coin until a few years ago, and started an experiment. I also used MS-70 as well. So far, coins that I did not stabilize after a dip retoned to some degree (not attractive toning). The ones I washed in MS-70 retoned more attractive with some real color. The ones I stabilized after both look fine. They were all UNC Kennedy and Franklin Halves in the MS-63 range.

So what's better for the final rinse? Acetone or alcohol? Does is depend on the coin (i.e. MS, proof, circ)?

Would like to see some additional input re: alcohol vs. Acetone

I use acetone as the final just because it dries so fast.
I can set it down and go on to the next coin.

urine, but onlyafter I've had lots of water to drink

So you do not need to rinse after an acetone bath? I always did a distilled water rinse.

Performance-wise [as in drying] there is no practical difference. I would advise the use of alcohol simply because its a lot less likely to contain impurities from the way it is handled and packaged. Purity requirements for "paint store" acetone are less critical than they are for topical use rubbing alcohol.
