Thanks for that recommendation. I've been using Moldzyme
(http://moldzyme.com). Physan 20 is somewhat cheaper, so it would be a
good choice if I need to wash down a large area. However, the MSDS is a
bit scarier than Moldzyme's -- but a lot less scary than older biocides,
e.g. old-fashioned Lysol (which was definitely carcinogenic).
I am happy to spray Moldzyme on anything that will tolerate being
sprayed with water. I detect no skin irritation, but I do wear gloves
anyway. It has a long-lasting effect, so for example lightly spraying
cardboard storage bins will retard mold growth for many months.

Yup, got that now. I just didn't have it quite soon enough. When I
did the job that made me sick I should have had such a respirator, and
also disposable coveralls.
