A) I wrote back when Mrs Doom was doing the research on how long the virus was capable of living on surfaces - and Wordsie is correct - I do quarantine all our paper mail. And clean EVRYTHING else down with hypochlorous acid before it gets into the inner sanctum. Us included (Halo fire and rescue shower is perfect. Works wonders).

7 days for plastic is now the accepted numbers. A whole freaking week as long as it (sarscov2) is exposed to air and changes in humidity. If it is inside a protected atmosphere with slight moisture available AND stable temps - Mrs Doom et al did find that they had 15 days as their max recommended sanitization time for plastic covered goods.


Here is another teams early efforts and findings. Look closely as the humidity / weather play a MASSIVE part.
