My results show that the Silvertize cloth really does inhibit bacterial growth compared to a cotton cloth, but that doesn't mean the Silvertize cloth will always be germ-free. I've also shown that a used Norwex cloth still had a lot of bacteria after hanging to dry for 24 hours. However, a Norwex and e-cloth seem to inhibit bacterial growth more than a cotton cloth does. You can order Silvertize cloths here. You can order elcoths here. You need to find a consultant to order Norwex. Please sign up for my email list if you want to be alerted when I post new results.
