I've decided on saying that the disinfectants "deactivate" the virion, so I can avoid the discussion about whether viruses are alive or not (probably not).

I'm not sure how to compare bacteria recommendations vs. virus recommendations.

I didn't know this before the pandemic, but: concentrated bleach expires, bleach solution expires, concentrated bleach lasts longer at room temperature, and thicker non-splash bleach is at a lower concentration than regular bleach. For ebola, CDC recommended to make new bleach solution every day:

I do 1/2 cup bleach per gallon, which is a little more than CDC recommends. We get everything delivered to the house now, so I mix up a fresh batch before we decontaminate that day's packages. Then I'll let that same batch sit, and I'll spray the next day's packages with it too. After that, I'm outside the 24-hour window, so I throw away the batch of bleach.

I'm watching carefully for any solid evidence indicating that we can relax our decontamination procedures, but I'm just not seeing it yet. Current understanding is that fomites are not the primary means of infection, but that coughs/sneezes/breaths from an infected delivery person onto the cardboard of a package can last up to 24 hours, and can last for days on plastic packaging tape.
