I don't mean to start another "a" thread / argument - but my $0.02...
Bleach is not the mold "cure all" many believe it to be.
Seems to work fairly well on NON-POROUS surfaces but on porous surfaces (e.g. canvas) mold will likely return.
Lots of links out there... here's on that comes up when you search whether bleach kills mold. Mold Removal and How to Kill Mold
Lot's of alternatives that work as well or better depending on the surface being treated. One of my favorites for mold & stains (especially red wine) is hydrogen peroxide - very useful on clothing, fabrics, furniture and it works equally well w/ blood stains
I have used the vinegar approach on canvas and it seemed to help prevent the rather quick return when I used just bleach.
