Joćo,
You should not use Canson, it's a terrible paper
for alt process. I know this paper is popular in Brazil, but there are other
brands, try Monval and your problems will be over.

Hi Francis,
The prints are inside a plastic bag and kept in a folder.
I also printed o canson 200g, aparently no grauing, but the prints aren't
that "old".
I can shoot some gray prints and put them in a web page for you to see
the efect.
I don't use trays exclusively for a unique process, but I wash them well
after.

Joao,
This is a long shot but when you said
stored in a portfolio did you mean an archival storage box (non-buffered) or
a photographer's portfolio with plastic protected pages?
I noticed a
duller brown after a night of dry down when using older VDB (made over 4
months previous).
Is there another paper you have printed on which
hasn't displayed the graying?
Would you be able to scan or photograph
a fresh VDB and one that has shifted after 20 days and post them to a web
page?
Are you re-using the same trays for different processing steps
or do you dedicate one tray for each of the clearing fixing
steps?

The silver image of VDB is said to be quite vulnerable
to attack (by say
pollution in the air), since the silver filaments of
VDB (if they have
that shape) are quite small, in general the smaller
the silver
filaments, the warmer/browner the image, and toning with
gold protects
these silver filaments..but also changes colour (for the
better IMHO...)
Did the white parts of the image change colour
(towards yellow) because
that would indicate that you did not fix
strong enough, change of colour
of the blacks could indicate that you
did not wash the fixer out enough
(I used also a hypo-clear
step)
...but I should stop, my experience with VDB is limited and
dated,
Best,
