Safe & Effective Carpet Cleaning (continued)
Preventing soil and dust from entering a building means less frequent cleaning and less chemicals.
Place large walk-on mats at building entrances.
Clean the mats frequently
Experiment with different textures and sizes to see what works best
Properly maintain vents that exhaust outdoors.
Push airborne dust back out of doorways by operating the heating, ventilation, and air conditioning systems so that the air pressure just inside each doorway is higher than that of the outdoor air.
