Foxing



No one really knows what foxing is, whether it's biological or chemical. Yes
it is disfiguring but in most cases that's about it. It is exaserbated by
high humidity and temp though... If you bleach it it will come back, worse,
because the rest of your paper will be whiter. Alcohol can be great for
mold, but not above 70%. The reason for this is that a higher alcohol
content dires out the shell of the mold spore, sealing it in until such a
time as growing conditions are better. 70% will penetrate the spore and
actually kill. You need those 30% water.
