The Norwex Antibac Microfiber Cloth claims to clean windows, countertops (including granite) and stainless steel - only with water. It also claims to remove bacteria.
"Inside is silver embedded within the cloth," says Debbie Cassman of Norwex. "Any germs are killed or destroyed by the silver within 24 hours of use."
Bridget Fisher, a microbiology lab coordinator, designed a scientific test in which several dozen sterile petri dishes were contaminated with e-coli bacteria.
A set amount of dishes were left untreated as the experiment's control. Several dishes were treated with a paper towel sprayed with a leading all-purpose cleaner.
Several were treated with a generic microfiber towel soaked with sterile water. The rest, treated with the Norwex Antibac Microfiber Cloth, also soaked with sterile water.
Following scientific method, Fisher exposed and treated the dishes, then put them in an incubator for 24 hours.
Twenty-four hours later, she examined and measured the amount of bacteria in each dish. She discovered the dishes treated with the paper towel and cleaner removed none of the e-coli bacteria. The generic microfiber removed 84 percent of the bacteria.
Then, Fisher dropped our jaws with the Norwex data.
"I found that the Norwex cloth could reduce the bacteria that we recovered from the surface by 92 percent," she said.
Fisher said the data was a revelation to her about what may really work in removing contaminants from household surfaces.
