Swiffer® is so yesterday

Disposable wipes are expensive and going straight to the landfills!

Last year, we spent $800 million on cleaning wipes, which would fill 6,300 semi-trucks that would stretch 48 miles loaded with 58,000 tons of synthetic polymer trash that is not readily biodegradable. Don’t do that!

Swiffer® has been around and many people like the convenience that the concept provides. Most people don’t realize that the Swiffer® was designed as a “razor-and-blades business model”, whereby the consumer purchases the handle assembly at a low price and must continue to purchase replacement refills and pads over the life of the product. The Swiffer® WetJet detergent bottle, for example, is designed to be near impossible to refill with generic or homemade cleaner.

That “reasonably priced” first purchase becomes an expensive refill, but you keep doing it because it is convenient to grab for that quick clean-up. There is a little known cleaning system currently in use at hospitals and patient-care facilities that is successful because it is a complete microfiber system that saves money, saves time AND prevents cross-contamination between patient rooms. Green Tiger is bringing this complete microfiber cleaning system to you to use in your home. The commercial-quality handle and frame has ergonomic benefits that will make cleaning a breeze. The microfiber mop cleaning pad is patented microfiber technology, designed to bring you a microfiber product that exceeds expectations.

There is a scientific study that provides data comparing the traditional cotton mop system to a microfiber system. Check it out here. Combine environmentally-friendly, powerful and concentrated cleaning products with commercial-grade cleaning tools, and you can start collecting art with all the money you are going to save.

You would pay $80.09 for 144 wet Swiffer cloths that might last you 7-8 months.

Scientific Study of Microfiber Effectiveness

The effectiveness of microfiber mops to reduce microbial levels on floors was investigated. The efficacy of microfiber mops were compared to conventional, cotton string mops in 3 test conditions (cotton mop and standard wringer bucket, microfiber mop and standard wringer bucket, and a complete microfiber system). Twenty-four rooms were evaluated for each test condition. (RODAC plates containing D/E Neutralizing Agar were used to assess “precleaning” and “postcleaning” microbial levels.)

THE RESULTS: The microfiber system demonstrated superior microbial removal compared with cotton string mops when used with a detergent cleaner (95% vs. 68%, respectively). The use of a disinfectant did not improve the microbial elimination demonstrated by the microfiber system (95% vs. 95%, respectively). However, use of disinfectant did significantly improve microbial removal when a cotton string mop was used (95% vs. 68%, respectively).

CONCLUSION: The complete microfiber system demonstrated superior microbial removal compared with cotton string mops when used with a detergent cleaner. The use of a disinfectant did not improve the microbial elimination demonstrated by the microfiber system.

Is microfiber more expensive to use?

New technologies, such as microfiber mops and towels, can significantly change the amount of chemicals, water, and labor needed to clean surfaces. Many of the reports on microfiber performance have come from hospital case studies documenting the use of microfiber mops on hard floor surfaces.

In 1999, the University of California Davis Medical Center (UCDMC) conducted a microfiber mop pilot program. The data recorded throughout the program yielded several beneficial findings, including: a 60 percent lifetime cost savings for microfiber mops, a 95 percent reduction in chemical and water costs associated with mopping, and a 20 percent labor savings per day [13]. Furthermore, the program found that the microfiber mops were just as effective, and in some instances outperformed their conventional counterparts. Within one year, the medical center completely replaced conventional cloth mops with the microfiber version in all patient-care areas.

Due to a decrease in water use, the lighter microfiber mops make custodial job duties less strenuous because they are much lighter, do not require mop wringing, and greatly reduce the need to change mop bucket water.

Since microfiber mops are easier and faster to use, the UCDMC

  • saved 638 hours per year for each worker, or about $7,665
    in wages [14].
  • The lighter mops also decrease the potential for occupational injuries, which translates into potential savings through reduced worker’s compensation claims filed and associated administrative time spent dealing with such claims.

As for performance, a report published in the American Journal of Infection Control reported that microfiber mops outperformed conventional cotton mops in microbial removal, 95% and 65% respectively [15]. This superior performance, combined with the 95 percent decrease in water and cleaning chemical usage seen by the UCDMC, makes a strong case for the adoption of microfiber mops for hard floor cleaning in business, government, and school buildings, as well as in hospitals.

Compare a traditional cotton mop to a microfiber mop

Using a traditional cotton loop mop for wet mopping in hospitals has been standard operating procedure in floor cleaning for healthcare facilities for decades. Recently, the healthcare industry has begun to look long and hard at evaluating a different method for cleaning hard surface floors within healthcare facilities with the hope of reducing chemical use, water use and increasing employee and patient health as well as improving overall cleanliness on site.

Microfiber mops are densely constructed polyester and nylon fibers able to hold 6 times their weight in water. Because the fibers are positively charged, it attracts and picks up dust (which is negatively charged), and these microfibers are able to penetrate the microscopic surface pores of any material.

Using the traditional cotton loop mop, it was required that the mop head and water be changed every two or three rooms to reduce the risk of cross contamination. This meant dumping gallons of water and chemical down the drain along with the hardship on employees of lifting the heavy bucket to do so.

Using the microfiber mops, the risk of cross contamination is reduced greatly in that you use one mop per room. With the microfiber system, 20 rooms can be cleaned using 1 and ½ gallon of water and 1 and ½ ounces of chemical.

The Silent Killer – Nosocomial Infections

by Benjamin Walker

When famed sports reporter Dick Schaap checked into Lennox Hill Hospital for hip-replacement surgery in September of 2001, he unfortunately received more than just a new hip. Schaap came out of the hospital with a serious infection that some three months later took his life. His death created a controversy when an ABC News report hinted that the infection might have been preventable.

Early in 2003, former U.S. Senator Daniel Patrick Moynihan went into the hospital for a routine appendectomy. Two weeks later, Moynihan died of complications from an infection he attracted following the procedure. These “Complications” have a name, and it is time to start using the proper terminology: nosocomial infections. Nosocomial infections are infections that patients acquire from hospitals. They also are infections that few hospitals are willing to discuss.

The U.S. Centers for Disease Control and Prevention (CDC) reports that roughly 2 million people per year acquire a nosocomial infection in the United States. Experts estimate that out of that 2 million, roughly 100,000 die from the infection. This incredible number is made all the more alarming when you consider that, based on CDC statistics, it’s an amount greater than last year’s U.S. deaths from SARS, terrorism, drunk driving, handgun violence, and AIDS combined.

So where does the cleaning industry fit into this dire situation?

The relationship between nosocomial infections and cleaning may be far more direct than most people imagine. In any facility, walls, floors, doors and fixtures can all be vehicles for transmitting bacteria. This spread can be especially dangerous in hospitals, where potentially deadly germs can be spread among patients whose immune systems are compromised by illness. Last October, USA Today published a story about the outbreaks of skin infections in team sports. Most of the athletes were diagnosed with a form of staphylococcus called methicillin resistant staphylococcus aureus (MRSA). MRSA is a type of bacteria primarily found in hospitals and nursing homes. It has been a problem in healthcare for nearly 20 years and is a common form of nosocomial infection. The CDC speculates that some strains of MRSA have become more virulent and thus may now spread more easily.

The infections reported by USA Oday were largely contained, but a few resulted in hospitalizations. And while most of the cases were acquired through direct contact and improper hygiene, improved cleaning processes were listed as a preventative measure. MRSA is not the only form of nosocomial pathogens. A number of other infectious bacteria can be contracted form the hospital environment.
In his book, Protecting the Built Environment: Cleaning for Health, Dr. Michael Berry writes, “80 percent of infectious disease is spread through direct contact; 20 percent of the risk domain, then might be associated with some part of the environmental exposure.”

The definition of direct contact is varied, but it is mainly described as people touching people and exposure to bodily substances. Although Berry says that most incidences of direct contact are the result of a lapse in basic hygiene, he adds, “Normally, when that occurs, you look around and you find the environment is disheveled.”

Berry continues, discussing elements of a healthy building environment and how they relate to custodial workers: “The cleaning professional has a key role in managing the indoor environment so that the many contaminants that cause sickness are removed from contact with humans. When contaminants are removed or minimized through cleaning, human exposures and risks are reduced. Cleaning is always the critical ingredient in maintaining a healthy building.”
By the numbers, the “20 percent of the risk domain” that may have a connection to environmental exposure accounts for roughly 20,000 deaths and 400,000 infections in the United States that could be traced to improper cleaning. The CDC has published articles on its Website ( promoting proper hospital cleaning techniques while numerous industry consultants and experts worry about the spread of nosocomial infections.

Perhaps it’s time for the cleaning industry as a whole to take a look at the gravity of this issue. The effects could resonate with manufacturers and distributors amore than they might think.

Supplier Role

The cold, hard truth is that many facility service providers – even those involved in the healthcare field, – do not truly recognize the value of cleaning. But with nosocomial infections finally beginning to receive their just notoriety, now could be a golden opportunity for the cleaning industry to demonstrate its professionalism by taking the time to discuss the issue with customers in the healthcare field.

Spend time with cleaning crews to make sure they are properly maintaining the hospital environments. Show crews and budget planners how the right products and equipment – properly used – can avoid cross contaminating surfaces. Not only will this demonstrate to customers that you genuinely are interested in their welfare, but also, it just might make them less eager to trim their cleaning budgets (which can only contribute to the health of your bottom line).

Potential Microbe Transmitters

A fomite is an inanimate object that serves to transmit infection from person to person. Doorknobs, railings, walls, floors, windows, and countertops area all fomites. Distributors should emphasize to their customers that to ensure a hygienic environment, all surfaces should be cleaned and properly disinfected. A sanitary, dry surface is the best protection against the spread of bacteria.

Routine maintenance and replacement of cleaning equipment where necessary is another suggestion distributors can make to help their healthcare customer identify potential nosocomial transmitters. Vacuum filters should be emptied, cars cleaned regularly, mop heads cleaned and replaced and clean rage sued at all times. An appropriate germicide should be sued with a proper disinfection technique.

Another potential culprit is improperly maintained janitorial closets. Mop buckets, for instance, do not always receive appropriate solution changes. A recent article by Katy Dix in Infection Control Today emphasized the importance of proper care of equipment in the prevention of the spread of infectious germs.

“If the cart originated in the janitor’s closet, Dix writes, “it was a surrounded by mops, buckets, and bottles of disinfectant or sanitizer. If these materials have not been cleaned properly, they will transmit whatever pathogens they carry to the cart, regardless of whether or not is has been appropriately cleaned after its sojourn through the hospital. This cart travels into reception areas, including the emergency room (populated with plenty of pathogens); operating rooms, intensive care units, pre-op and post-op recovery areas: the cafeteria and break rooms, restrooms and laboratories.”

While it is important for custodial professionals to ensure that equipment and materials are properly disinfected in the hospital environment, they also need to make sure that they are taking proper measures to protect themselves. Proper hygiene and use of personal protective equipment may help protect workers from coming in contact with infectious pathogens and can hinder the spread of bacteria.

The annual death toll is reason enough for the cleaning industry to pay close attention to nosocomial infections, especially if 20 percent – or more – of these infections may avoided through proper cleaning techniques.
