Knowledge is power
 
Facts 
  • Almost 5 billion pounds or over 690 million square feet of carpet are sent to landfill each year (Source: US EPA)
  • Billions of liters of fresh water is used for carpet cleaning each year
  • Millions of kilowatt hours of electricity is used to dry carpet that is wet cleaned through the HVAC system and fans
  • Wet carpet cleaning contributes to millions of dollars of mold remediation because of improper drying procedures
 
 
Terms
 
Hard Surface vs. Soft Surface
  • A hard surface floor does not trap and hold dirt
  • A soft surface floor/carpet does trap and hold the dirt.
    • A carpet can hold its own weight in dirt and still look good, i.e. 2 pounds of dirt in a 30 oz./sq.yd.
    • A carpet can hold 2 times its weight in dirt before people begin to notice, i.e. 4 pounds of dirt in a 30 oz./sq.yd.
  • 90% of the dirt that gets on a carpet in a building is tracked on by people's shoes, from inside or outside hard surfaces. Airborne dirt and dust makes up the other 10%, coming in through windows, doors, airborne cooking grease and the HVAC system
 
Micron
  • 1 micron is a millionth of a meter or 1 inch divided into 25,400 parts
  • An average size of most bacteria is 2 microns
  • GreenDry Carpet Cleaning uses eVAC with a 6-stage filtration system that traps particles as small as 1 micron in size at 99% efficiency (optional: add a HEPA media filter can trap particles as small as 0.3 micron at 99.97% efficiency)

Spot, Spill, Stain
  • Spot (removable stain) - a substance that is on the fiber or yarn surface and can be
    removed using correct spot removal procedures.
  • Spill - a wet substance that is on the fiber or yarn surface and can be removed using correct spot removal procedures.
  • Stain - a subtance that has permanently damaged or changed the color of the fiber. It cannot be removed.
 
 
Sterilizing, Disinfecting, Sanitizing
  • Sterilize - to kill all living bacteria and fungi and their spores via
    1. Steam under pressure for at least 12 minutes
    2. Ethylene oxide gas for 1-2 minutes
    3. Chemical sporicide for 3 or more hours
    • It is not possible to sterilize carpet
  • Disinfect - to kill all living bacteria but not their spores via
    1. Immerse in boiling water for at least 2 minutes
    2. Immerse in a chemical germicide (e.g. alcohol, chlorine) or bactericide for at least 10 minutes
    • It is not possible to disinfect carpet
  • Sanitize - does not kill microbes but to reduce the total number of microbes by cleaning, e.g.
    1. Taking out the garbage
    2. Washing the dishes
    3. Wiping an area with a soapy cloth
    4. HOST cleaning the carpet
    •  When you clean a carpet with GreenDry Carpet Cleaning, you sanitize it
