House and clothes are kept clean. Wet shower curtains are stretched out after every shower. Moisture-absorbing materials are used during times of high humidity. Some examples are silica gel, activated charcoal, calcium chloride, moth ball crystals and kitty litter. A low-wattage light bulb is kept on in closets to dry out the area.
Heating system is turned on when the humidity is very high.
Leather goods are waxed. Shrubs that grow close to the foundation are trimmed so that there is 1 foot of air space around the house. Mildew is cleaned from any exterior area of the house before repainting. In many cases, a simple mixture of 1 gallon water and 1 cup liquid chlorine bleach is an effective mildew remover. In other cases, you may want to use detergent, ammonia, white vinegar, washing soda or some combination of these ingredients.
