Mold is a type of fungus that spreads by way of spores. These spores make their way onto moisture-rich surfaces which are perfect sites for them settle and grow. In addition to being eyesores, mold can also pose a danger to the health of people exposed to them. This is the reason why removing mold is very important.
Wooden outdoor furniture such as tables and chairs are prone to mold growth, thanks to their being constantly exposed to the elements. Treating your wooden outdoor furniture with WD-40 will stop moisture from seeping-in because of its water-displacing properties, preventing mold from growing.
