(No products are endorsed or recommended in this post, it is publicly available information only; please contact your local regulatory body for cleaning guidelines.)

Here are a list of products, which are listed as approved by the EPA, as “Disinfectants for Use Against SARS-CoV-2”, sorted by contact time.

 

Contact Time

(Note: some of these are commercial grade products not suitable for home use, or on all surfaces.)

What is contact time? The time that the disinfectant needs to stay wet on a surface in order to ensure efficacy. As a benchmark, the CDC indicates that most EPA approved agents use a contact time of 10min. in hospitals (link here)

According to this data (current as of 4/21/2020), Spruce-Ups by the Clorox Company is listed as having the shortest.

However, we were not able to find the commercial formula for this product, suggesting that it may no longer be available.

Why does the EPA list it then? We will ask and report back with any updates!

Post questions, Thanks for reading
