I would make the case that many professional cleaners employ the use of an extremely green concept every day in their cleaning. One of the most overlooked ‘green” contributions that carpet cleaners make is in the use of heated cleaning solutions with their truckmount or high performance portable extractors. Several independent and peer reviewed scientific studies have confirmed the value of heat in the carpet cleaning process. Yet this remains one area of carpet cleaning where gross misconceptions still exist. Hotter cleaning solution increases the chemical molecular activity of the cleaning chemical you are using (including water). This basic chemistry concept can be confirmed in basic science concepts by the Argonne National labs (http://www.newton.dep.anl.gov/askasci/gen01/gen01759.htm) . Increased chemical activity means you will need to use less chemical to clean. Dr. Michael Berry, author of the book Protecting the Built Environment: Cleaning for Health, found that heat simply improves cleaning’s effectiveness. “Even without soap, small amounts of grease will dissolve in water, [but] the amount increases in hot water, sometimes ten-fold,” he says. There is nothing “greener” than a reduction in overall chemical usage.
Hotter cleaning solution contributes to a healthier indoor environment. Dr. Michael Berry and his associates, on behalf of the United States Environmental Protection Agency, did two groundbreaking studies measuring the impact of deep restorative carpet cleaning (utilizing hotter cleaning solution) in 1991 and 1994. The “Denver” Study in 1991 and the “Frank Porter Graham” Study in 1994 greatly advanced our understanding of the interaction between cleaning and the indoor environment. The “Denver” Study mainly looked at whether they could actually even measure particulates, gas phase organics, and biological contamination in carpeting before, during, and after carpet cleaning. The “Frank Porter Graham” Study was a collaborative effort that involved participants from the cleaning industry utilizing “best industry practices” and deep cleaning methods for on-going cleaning and maintenance in a Child Development Center on the campus of the University of North Carolina at Chapel Hill. Airborne dust contaminants were reduced by 52%. Total Volatile Organic Compounds decreased by 49%. Total bacterial was reduced by 40%, and total fungi declined by 61%. If the measurement of “green” includes making the indoor environment “healthier,” the contributions of hot water in the cleaning process cannot be overstated.
One of the points that I brought up with one third party certification group that seems to get completely overlooked by organizations writing policy that affect our industry has to do with the way that most modern truckmounts work. The fuel consumption used to power a truckmounted carpet cleaning machine, whether it be a slide-in or direct drive unit is going to exist in order to operate that unit. In most cases, it runs on gasoline. The heating of the water in a heat exchanger truckmount works by capturing heat from other sources (engine, blower, radiator, etc…) that are being powered anyway. The hot water created by a truckmount does not require the use of any additional resources beyond those required to run the truckmount. Using the fuel source for dual benefits – what could be greener than that?
CleanMaster has a complete line of products that are manufactured utilizing ingredients recognized as “green.” These include products that have earned our prestigious SafeClean designation, which was initiated back in 1991 long before Green became a buzzword. SafeClean™ is HydraMaster’s long time trusted designation for cleaning solutions formulated with the latest technology in environmentally preferable “green” technology. SafeClean designated formulations meet or exceed industry ingredient guidelines for green cleaning solutions. The SafeClean designation goes well beyond traditional definitions of what a green formula should be like. It takes into consideration utilizing sustainable and renewable ingredients, environmental and health impact footprints on the indoor and outdoor environment, and perhaps the most important consideration of all- removing and extracting the soil from the surface being cleaned.
