Zoono spoiler results

Zoono Ultra claims to kill norovirus and is a good hand sanitizer if you use a lot of spray to really cover your hands (10 sprays on each hand) and your hands are not visibly dirty. It does not do quite as well as Zylast hand sanitizer in my experiments. I have not been able to show that Zoono (or any hand sanitizer) continues to work for extended periods of time. Zylast is available on their website www.zylastdirect.com. Use coupon code StopNorovirus to get 10% off your order.  Zoono is available here on Amazon. Thank you. --Annie Pryor, Ph.D.
