Testing Confirms Efficacy of Clorox® Products Against Variants of SARS-CoV-2 (COVID-19) on Surfaces

April 9, 2021

Third-party testing results support scientific understanding that disinfecting products that kill COVID-19 are effective against prevalent strains of coronavirus on hard, non-porous surfaces.

OAKLAND, Calif., April 9, 2021 – Clorox today announced the results of third-party testing, confirming the efficacy of several of its most popular disinfecting products against the three most prevalent variant strains1 of SARS-CoV-2 originating in the United Kingdom, South Africa and California, U.S. This testing follows a recent announcement from the U.S. Environmental Protection Agency (EPA) stating that genetic changes to the virus do not impact the efficacy of disinfectants and all disinfectants approved to kill SARS-CoV-2, the virus that causes COVID-19, will kill new strains of the virus.

“As new SARS-CoV-2 variants circle the globe, people need to have confidence and trust in the disinfecting products they rely on to keep their homes, businesses and loved ones healthy,” said Denise Garner, Senior Vice President and Chief Innovation Officer, The Clorox Company. “It’s common for us to test claims against multiple strains of a pathogen, such as influenza, to demonstrate product efficacy. Validating the science is a big part of our commitment to people – ensuring that our products help protect their homes and businesses.”

The testing was performed by an independent testing facility following ASTM E1053-20 with the viruses dried with a 5% organic soil load on a hard, non-porous surface. Clorox plans to submit the findings to the EPA for review. Products selected for testing represent the broad spectrum of Clorox disinfectants available for use in the home, businesses, schools, restaurants and healthcare facilities.

The initial wave of test results includes the following products, with more results expected in the coming weeks:

Clorox offers a number of hard surface disinfecting products approved to kill SARS-CoV-2, the virus that causes COVID-19, under the EPA’s List N, and will continue to be used to help fight the spread of COVID-19 safely and effectively.
