Does anyone have experience with this?

your climate and precipitation will provide a better answer to you if
you ask your good neighbors how they handle this.
otherwise get a garden hose attachment or a gallon pump up sprayer and
lots of bleach, figure on diluting to 3 percent bleach.
if you have high humidity at night perhaps run the fans if humidity is
lower in the daytime.
if you want to dive into the research, there's a world of knowledge
for your home depending on what climate you live in. free, at:
