Consider placing a trash receptacle near the restroom door.
Many people use a paper towel to keep from making contact with the door handle after washing their hands.
If there is not a receptacle near the door the paper towel typically ends up on the floor.
Stop Dirt at the Door
Place mats in front of doors and keep them clean.
Stopping dirt before it enters your facility minimizes wear and tear on your carpet and floors, plus it keeps dust to a minimum.
International Sanitary Supply Association (ISSA) statistics state it costs you as much as $500/lb to remove dirt and dust from your facilities. This number is based on labor hours spent dusting and vacuuming.
