If it isn't Clorox (or another brand with an EPA registration #) it is not suitable for disinfection of infectious agents. An EPA registration number is required for all disinfectants. 


If it is Clorox (or another company has registered theirs w EPA during the pandemic) then I would find the lot # on the bottle and call the company.  They can tell you if it has expired as a disinfectant.
Good luck w this!

Hello,

I was wondering about using old stocks of bleach for disinfecting in bio labs. The bleach is about 2 years old and has never been opened. I am not sure if it is industrial or commercially available bleach. Any advice would be appreciated.
