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.
No matter what you do, you’ll still need to vacuum regularly. Have your carpet PROFESSIONALLY CLEANED at least once or twice each year!
