crazing/mildew(?) on old low fire ware

I have recently been asked about some crazing just noticed and darkening
of the areas
on some lovely old low fire ware. I believe the set was purchased in Rio
some 40 yrs ago, is used sporadically, and had been stored for most of
this year, wrapped carefully and stored. The plates are signed "PRADO".
The entire piece is glazed, ie. no waxed or glaze-free foot ring.

Because these pieces are so cherished, I hesitate to try microwaving
them to theoretically kill mild I think is in the crazing, particularly
with the thread we've been hearing about low fire disinigrating or
cracking apart in the micro.

Any suggestions? How about boiling ? Wouldn't this shock the stuff too
much? Soaking in chlorox water or vinegar water?

I just know someone out there in Clayart Land can help me with this one.

My friend, and owner of this lovely pottery, will love you for it , too.

TIA, Pam in drizzly Seattle

When I was a paramedic we used a 10% solution of bleach and water to clean
the ambulance. You should let the solution sit on the surface to be cleaned
for at least 10 minutes. If you soak the ware in the solution for a bit
longer it should work it's way into the crazing and kill the bacteria you
believe is there. I hope this helps.
