On vacation I managed to drop a circ pol into the water. I recovered
it about 20 minutes later (was under a dock and hard to access).

It is the Minolta circular polarizer from the 90's. (72mm).

I immediately rinsed it off and let it dry, expecting there to have
been water seepage into the pol between the two elements.

Yesterday I took the polarizer apart, to a degree.

The outer ring and the inner pressure ring segment came off with no
problem, but I can't separate the two elements. I also suspect that
NO WATER entered between the two elements at all. I certainly can't
see any "stain" or anything in there...

Anyone with advice on what (not) to do?

I'm leaning to cleaning the accessible surfaces and not attempting to
separate the elements.

Alan,

Some CP's are made from 2 pieces of glass with the polarizing film
sandwiched between them. Do not try to separate the two halves or you
will ruin the polarizer.

Ah. That explains what somebody replied on another forum. Thanks.
