We tend to ignore doors, doorways, and light switches when it comes to cleaning, although they're some of the most-touched spots in our homes. If you take a second to look at them, you might be shocked to find a slew of hand marks and fingerprints. Take a cleaning solution (soap and water, bleach, whatever you like), and spray away those dirty marks. Even if you don't have marks, it doesn't hurt to sanitize these highly trafficked hand areas.
