Having an extensive background of work in cleaning everything from business suites to my personal home to bed-ridden patients rooms, I was a little skeptical of the anti-bacterial and "ultimate clean" claims. I MUST say, however, that after extensive testing of the various surfaces that I had cleaned with both the "best" chemicals on the market and the Norwex products......drumroll........ The Norwex products cleaned more efficiently, and left less standing bacteria on the surface! (There were protein tests and other test swabs which were carefully inspected under a microscope by not only me but also by other concerned nurses and moms to come to this conclusion!) The flu illness is a thing of the past in my home, No more severe migraines from the harsh chemicals that were once used in my home, No more asthma flare-ups in my children from chemicals being used in my home, No more rashes for my baby from crawling around on the chemical-laden floors! OVERALL, Norwex has made our family more than happy!
