Holy Chicken!! Check out this demo using 3M Protein Tests. We tested a surface after smearing raw chicken on it to see if a surface is truly clean after using a Norwex Enviro Cloth. Bacteria grows if there is protein left on a surface. These 3m Tests can detect even the slightest amount of protein left on a surface. This demo will show how the Norwex Enviro Cloth leaves a surface clean and clear. Happy Cleaning!
