Household Disinfectant

There is a 2009 paper in the American Journal of Infection Control that tested common household disinfectants using the mouse hepatitis virus strain 1 (MHV-1) as a surrogate for HCoV. MHV-1 is Betacoronavirus  and is commonly used as a surrogate. They tested the active ingredients of 5 common household biocidal agents, Lysol, Dettol, household bleach, Clean & Smooth antibacterial soap, and Pine-Sol.  The active ingredients were respectively,

0.100% Alkyl dimethyl benzyl ammonium saccharinate/79.0% ethanol (undiluted)

4.8% Chloroxylenol (PCMX) (1:40)

5.25% Sodium hypochlorite (1:25)

0.200% Triclosan (1:4)

15.0% Pine Oil (1:64)

All but the 0.100% Alkyl dimethyl benzyl ammonium saccharinate/79.0% ethanol showed a 4log₁₀ reduction (required by FDA). The 0.100% Alkyl dimethyl benzyl ammonium saccharinate/79.0% ethanol only showed a 3log₁₀ reduction.

They used a 30 sec contact time for these tests.

So that leaves you with 5 choices:

1. See if you can purchase the active compounds in the solutions you are presently using.

2-5) Use one of the compounds shown in this paper, again with the caveat that you need to be able to purchase them.
