White distilled vinegar is an eco-friendly alternative household cleaner. It’s been said that it is effective at killing most bacteria and germs. I have cleaned the mold out of shower drains by pouring 2qtrs of boiling water into the drain following that with 1/4C of baking soda and one cup of Vinegar... wait an hour and pour another 2 quarts of boiling water in the drain. I have also mixed vinegar and baking soda in a spray bottle to use on the tile and grout. It is very effective without the harness of bleach! And it does not have a strong odor.

Larry Chiaramonte, Allergy & Immunology, answeredHouses that are prone to mold can be painted with a product like Caliwel, which has been approved by the EPA (Environmental Protection Agency) to kill molds on contact. It is applied like any paint and can be active for up to six years, although contractors of our acquaintance are dubious of this claim.
