While cooking, use exhaust fans to reduce cooking fumes and to limit moisture. Keep all food in sealed containers and dispose of expired, out of date items. Seasonally, wipe down the inside of refrigerators and utensil drawers. In all of these kitchen areas, baking soda is the best option for an all-purpose cleaner.
Having an exhaust fan is an easy way to control the moisture in the bathroom when showering. Avoid use of aerosol sprays such as hairspray or bathroom deodorizers. And, make your own natural and effective bathroom cleaner using a 50/50 vinegar and water mix or baking soda and water paste.
Basements:
Regularly check for water damage or leaks and use a dehumidifier to reduce dampness. If mold or mildew is spotted, spray straight vinegar on the wall, let it dry, and do not rinse.
