The TV News Lab Test: Andy, Will It Work?
Back on September 24, 2013, Andy Wise of Action News 5 in Memphis put the Norwex Antibac cloth on his consumer segment, Andy, Will It Work? What I appreciate about this one is that the station didn’t just watch a demo. They had the test designed by Bridget Fisher, the microbiology lab coordinator at the University of Memphis.
Here’s how the station described it. Several dozen sterile petri dishes were contaminated with E. coli, and some were left untreated as the control. The rest were wiped one of three ways:
- a paper towel sprayed with a leading all-purpose cleaner
- a generic microfiber towel soaked with sterile water
- the Norwex Antibac cloth, also soaked with sterile water
After 24 hours in the incubator, the paper towel and cleaner had removed none of the E. coli. The generic microfiber removed 84 percent. For the Norwex cloth, Fisher told the station, “I found that the Norwex cloth could reduce the bacteria that we recovered from the surface by 92 percent.”
One detail matters a lot to me, because I want you to have the honest picture. Fisher explained that the silver in the cloth should help it remove bacteria from a surface, not kill or destroy them. That’s the point I always make too. Norwex cleans by picking up and holding onto what’s on the surface, so you can clean without potentially harmful chemicals.
Keep in mind this was one TV station’s test from 2013, with a cloth Norwex has since updated. In my opinion it’s still a great illustration of why a good cloth beats a paper towel. If you’d like to understand what’s going on inside the fibers, I explain it in how Norwex microfiber works.
What Norwex Says About Its Cloths Today
Norwex’s own wording is that its microfiber can physically remove up to 99% of bacteria from a surface using only water, when following proper care and use instructions. That’s removal, not disinfecting.
The silver-embedded fiber is called BacLock®. According to Norwex, BacLock is an antimicrobial agent solely intended to protect and self-clean the cloth by inhibiting growth of odor-causing bacteria, mold and mildew. BacLock does not protect people from disease-causing pathogens. In plain terms, it keeps your cloth fresher between washes.
