Wexford Labs has generated data showing its CleanCide Wipes (EPA # 34810-36) and Purefexion/Wexford Wipes (EPA # 34810-37) are effective against SARS-CoV-2, the virus that causes COVID-19, at 30 seconds. According to the data, the wipes demonstrated a 3-log reduction against the virus. The wipes were tested in compliance with “Disinfectants for Use on Environmental Surfaces, Guidance for Efficacy Testing,” the EPA’s threshold for deeming a disinfectant effective. (The data is intended to be submitted to the EPA for review to include claims of disinfection against the virus on the label.)
Microbac Laboratories, Inc., an independent laboratory that performs environmental, food, and life science testing for businesses, performed the efficacy testing using a multi-step process. First, the lab applied the virus to a surface and let it dry. Then, they wiped the surface with a CleanCide/Purefexion Wipe and left the carrier undisturbed for the contact time. The remaining liquid was neutralized and applied to cultured host cells and allowed to incubate for 4–9 days. The remaining viable cells (if any) indicated how effective the liquid was in inactivating the virus.
