Heavy curtains do a great job to block out light and insulate windows during the chilly winter and hot summer. But over time, drapes needs to be cleaned and sterilized to help maintain a healthy indoor air environment. One easy way to keep mold, mildew, dirt, germs and dust mites at bay is to use a hand-held steamer to clean your drapes. Using just tap water, hot steam can deodorize and sanitize your drapes without having to be removed. Just plug in the steamer and clean away.
