Set doormats at every entryway and ensure that everyone wipes by hanging a friendly — or cheesy — sign as a reminder; “Please be Sweeties and Wipe Your Feeties.” Even if family members occasionally forget to wipe, the mats will catch some of the dirt as they walk over them. Vacuum thoroughly at least twice a week by running a strong-suction vacuum cleaner with a rotating power head over the floors. Have all family members remove their shoes at the door. You can keep slippers available at the door for everyone, including guests.
