Muc-Off Anti-Bacterial Equipment Cleaner is a QUAT based cleaner. Quaternary Ammonium Compounds are the active ingredients found in the majority of surface sanitizing and disinfecting products, chosen for their effectiveness against a wide range of bacteria, molds, fungus, and viruses. Very few sanitizers, whether alcohol-based or QUAT based, will have undergone efficacy testing against viruses. The reason for this, it is widely accepted that enveloped viruses are easily killed by correctly formulated alcohol sanitizers and by correctly formulated QUAT based sanitizers. While the product itself has not been tested against enveloped viruses, what we can say is that the Muc-Off Anti-Bacterial Equipment Cleaner contains 50 times more QUAT than is deemed necessary to kill enveloped viruses.
