I have a feeling all of this (including the responses that have followed)
depends a little on the actual material the mouthpiece is made of. I've been
using straight vinegar to clean my mouthpieces for 40 years - many of those
mouthpieces necessarily older than your 1998-9 Selmer and definitely made of
hard rubber of some kind. Do you know what your C85 is made of? I'd have
assumed it was some kind of rubber, but I don't really know what Selmer was
using in the late 1990s. The white deposits have always come off of my
mouthpieces easily with vinegar, and I've never turned a mouthpiece green.

For the record:

A ~1 hour soak in a 5% solution of room temperature (~78F) distilled
white vinegar did not remove the white/tan deposits and turned my
Selmer C85 mouthpiece green. In addition to turning the region below
the liquid green, fumes also turned the portion above the liquid line
green. The portion of the submerged facing also became paler. My
mouthpiece now has a vinegar induced "suntan". The cork was not
submerged.
