Ray: The lens can be disassembled - carefully, but I would recommend a
service facility of good repute.  Opening a lens usually costs around
$80.00US and can be well worth the cost depending on the lens.  Your
description sounds a bit like slight deterioration of the cement between the
elements.  This sometimes looks like orange peel when observed at high power
with transmitted light.  You may well get by with this condition depending
on your expectations.  Sometimes a little flare (which is the normal result
of the type of "fogging" you describe) is actually beneficial - depending on
the subject.
