Re: [ARSCLIST] Growing things...

I have heard that the only way to really kill mould is with Javex
solution. I don't know much about how to clean mould from paper; you
should try giving the people at the archives a call? I hope you have
removed the tapes and sealed them off in plastic baggies. If you insist
(your client) on keeping the boxes, I suggest that you seal them off,
if you haven't already done so, and if you do any cleaning of them,
that you do it under a fumehood.

Perhaps this is self-evident, but I just spent a few months cleaning
mouldy discs (with discwashing solution _not_ with Javex thank you),
and let me tell you, life under the right size fumehood made a world of
difference. Mind you, I wouldn't like to repeat the affair if I could
avoid it.
