Spoiler Results

My results showed that a used Norwex cloth still had a lot of bacteria after hanging to dry for 24 hours. The silver in the cloth might be killing some bacteria, but I can't tell.  The Silvertize cloth did have significantly less bacteria after hanging dry for 24 hours so the Silvertize cloth is probably killing some germs. Please sign up for my email list if you want to be alerted when I post new results. Also, please use my Amazon affiliate links, like this one, when you shop on Amazon so I can earn money to buy agar plates and do more experiments. Thank you!--Annie Pryor, Ph.D.
