Anyway, my sister has black mold growing on her sidewalks, patio, and
driveway concrete.

So many people have reported the common ways that fail, that something
radically different comes to mind. Given that situation, I would head
to the boat shop and get some antifouling marine paint. Ending up with
a brightly colored sidewalk might be a small sacrifice to end the
annoyance and hassle of mold removal. Might even start a trend.

People are making too much of this. Bleach and water will take care
of it but of course it can return in time so in that case you just do
it again. You can use a simple spray bottle to do this job. It
doesn't need that much spray if you have enough bleach in the
solution. And I live in a Houston suburb so I can speak from
experience about this stuff.
