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.

Bingo! - "If it ain't broke, don't fix it."

Yes, but if water gets from there into his LNB it will break and its a lot
more expensive.

OTOH IIRC these [de]polarisers are very dumb and consist of a lump of
plastic in a the waveguide..

Well, it certainly doesn't hurt to dry it out well, and store it with silica
gel of some other drying agent. but I am reminded of the many times as a
repairman, I was posed with an intermittent problem, where the customer
said......"It failed yesterday, so can you fix it" ? Well, other than
checking out those things, (adjustments and etc. ) that might cause the
problem, there is really little that can be done unless the machine if
failing frequently.It is difficult to find the cause of an intermittent
problem for this reason.
