It’s no surprise that one of the easiest ways to keep your home as healthy as possible is to leave your shoes at the door. Shoes can drag in pesticides, chemicals and dirt, so going barefoot inside is a simple way to keep it clean. But before you take off your shoes, be sure to give them a good wipe on a doormat outside. By placing your doormat vertically at the door, you actually get better traction when wiping your shoes across it. It picks up more dirt and other grime, which helps keep your shoes cleaner.
