Physan-20 Kill Coronavirus?

[Subrosa]

I'm certainly not suggesting you simply run out, buy and use it, but a 1.5% solution of glutaraldehyde is available at most pet stores labeled "Flourish Excel". Glutaraldehyde is used for cold sterilization of surgical instruments, and surfaces in laboratory environments. I would strongly suggest you look into the compound yourself before using it, and of course it's suitable for external use only!
