5. Cut down on dry cleaning. The dry cleaning process uses harmful chemicals that linger on your clothes after you bring them home, so cutting back on trips to the dry cleaner is a good way to reduce toxins in your home. Try hand-washing some items (or use the hand-wash cycle in your washer) and dry flat. And try to choose clothes that don't need dry cleaning. You can also search for a green dry cleaner in your area; they should avoid the most harmful dry cleaning chemicals, but ask to be sure what methods they use.
