How to Clean Old Mildew From Wood

Mildew is white to bluish in color and grows in areas with excessive moisture and little ventilation. Mildew will grow on almost any surface that it can feed from, including wood. Along with an unpleasant musty odor, left untreated, the fungus will cause considerable damage to the surface it is growing on. Increasing ventilation and light to enclosed spaces will decrease the chances of future mildew attacks. While prevention is best, removing mildew must be done as soon as possible to stop the fungal growth. Following the process allows you to clean new and old mildew from wood surfaces.
