Unless you live in New Jersey, you probably touch this ultra-germy item on a weekly basis at least. A University of Arizona study sampled gas pumps and found that a whopping 71 percent of them contained some type of bacterial contaminant.
Clean it: If you don’t want to wipe down the pump before you use it, definitely keep hand sanitizer in your car so that you can bust any germs you may have picked up while filling up. Or consider wearing gloves to shield yourself from the germs.
While you’re getting a ride to your desired floor, germs might be hitching a ride on your hands. A University of Toronto study found that elevator buttons in public spaces like office buildings and hospitals could be harboring more germs than toilet seats.
Clean it: Maybe you don’t want to stand around your office building and wipe down the elevator buttons, and that’s fair. But you’ll probably want to wash, or at least sanitize, your hands once you’ve reached your floor. These common house cleaning mistakes can actually make your home dirtier.
