Neutralizing surfaces before slabbing......

Do the grading companies, specifically PCGS do anything to neutralize the surfaces of a coin before slabbing the coin? You would think it would be in their best interest to do so, as there is no way to know how the coin was handled in the past. There could be a fresh finger print, or small drops of saliva from a conversation that took place over the coin. Once the coin is slabbed these nasties could turn into ugly spots or toning on the coin that could reflect negatively on the company. Personally, I always give my submissions a soak in acetone prior to sending the coins in, just in case.

Would you like to expand on that?

Will dipping ASE's actually prevent milk spots?
Worry is the interest you pay on a debt you may not owe.

Yes it will if it is done BEFORE they become visible to the eye; or so I'm told. It has also been said here that coins that are predisosed to spotting can be identified by looking at them under a halogen flashlight and the spots if present will show then. I believe they can be dipped off with Ezest at this point. Once set enough to become visible, all bets are off.

Well, I'd hope it wasn't a conservation on conversation, I mean a conversation on conservation.

Sometimes I wish the surfaces were neatralized but most of the time - no.

This is usually a result of not proper rinsing.
