While your bathroom is far from contaminant-free, studies indicate that the kitchen might actually be one of the germiest spot in your home, with dishtowels and sponges topping the list of germs hot spots. In the kitchen and elsewhere in the home, countertops, cutting boards, sinks, handles and knobs, and light switches are a few other germy spots. To keep things clean, start with good habits like washing your hands well after using the bathroom or handling raw food. Always thoroughly clean cutting boards, wash dish towels often, and clean or replace sponges regularly to avoid accumulating bacteria.
Run your kitchen's exhaust fan while frying or sautéing (and leave on for an additional 15 minutes) to trap cooking-related indoor air pollutants; and change your heating and air conditioning filters regularly. When you clean, choose non-toxic cleaning products to avoid polluting the air inside your home. Try home-made mixtures using baking soda and vinegar or find alternatives to toxic cleaners at Environmental Working Group's Guide to Healthy Cleaning or by using the Environmental Protection Agency's Safer Choice labeling.
