I think Dario is saying that because of the UV effect, he can use a more
diluted bleach solution and therefore leave less residue and incur less
long-term damage from the diluted bleach. The article he sent made it pretty
clear that some damage will be inevitable with any amount of bleach. But it's
important to note that most paper is made with bleach to begin with --
that's what makes it white. Paper in its raw form tends towards being gray to
brownish, depending on the wood pulp used and the cotton added (called
"rag content ) -- if any -- during the manufacturing process. But bleach is
what is used to make common paper white. Exceptions are things like rice paper,
but the type of paper used for most printing has some bleach in it from day
one.
So, I think killing a problem like a fungus -- which can grow and get
worse over time -- by adding a tiny amount of additional bleach to the paper (in
selected spots) is a good trade.

So bleach will not harm the poster as long as it's a mild solution?
Thanks
Kirby, Thanks Susan,
I guess there is a lot of thoughts about Foxing,
somewhat a general term
for Fungi or Ferric oxide.
I treat them both
with no respect.
We all have our different ideas what works well,
wich is fine.
I always used this old paper restoration trick ( UV )
combined with a
mild Bleach bath. I can see the magic happening in front
of me, it's
fantastic.
Hey!! did you guys know that most large
paper tanks like Museum,
Libraries and Archives use UV beams in their air
ducts.
Very powerful beams that acts like filters, it will zap air
born
particles like mold mildew dust, anything that flows through that
could
be potentially harmful to paper, crazy
huhh?
Best,
Dario.
