Here are a few tips to help keep that carpet dirt outside and off your carpet and rugs: ADD A WELCOME MAT The larger the mat the better. Something nice and thick in front of the door. If that doesn’t work, you might try a mat that says BUZZ OFF! TRY A ‘NO SHOES’ POLICY It can be tough to enforce, but once family members get used to slipping off their shoes at the door, it can make a huge difference with carpet dirt. USE JUST ONE DOOR Especially during bad weather or dusty days, you only have one area to keep clean.
