OH! You mean THAT kind of
cleaner. Sorry Kurt. I was thinking... pest control.
Mold is a pain because it's one of those microorganisms that has survived comet strikes, hyper-eruptions and all manner of events that usually end species. It's probably going to outlast cockroaches.
Whatever you use has to be a
fungicide- a compound that is deadly to fungus and molds. Here in Mississippi we have lots of fungi and mildew and fight the same battle.
Indoors you have to fight the cause of the mold first and then attack the fungus. Mold and mildew thrive where there are damp conditions, humidity and a substrate on which they can live. This can be nearly anything- plastic, stone, concrete, brick, etc. Mildew like to live in things with micro pores like wood and stone where it can hide. First of all
get rid of the moisture. Look for leaking pipes.
Clean the area where the mold lives/kill the mildew.
Paint the area where the fungi lives with an anti-fungal paint like Kilz.Some stuff you'll need:
Krud Kutter is a pre-painting treatment for household surfaces. It Kills and cleans mildew and prepares the surface for painting.
Kilz is a brand of mildew proof paint and primers. If you've got mildew problems, kill the mildew and clean the surface and then paint it with Kilz primer.
Zinsser makes an excellent waterproofing paint which work well in basements.
Another way to clean mildew is anti-mildew compound in a pressure washer. Good for taking mildew off of siding, concrete.
