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.
