Well you're in luck because I said virus (accidentally) but I really meant "bacteria" - I don't think viruses can form spores, but who knows what we'll find. There are a lot of hijackings of cellular machinery that happen, and maybe we'll find one that uses a bacterial spore as a stealth capsule.
There are indeed bacteria which can survive high bleach concentrations. It was a minor nitpick.
I wound up reading about some particularly resilient strains of c diff and wow, that's spooky stuff.
But I bet if you weren't worried about etching or skin safety you could find a concentration that would handle those little buggers. It's the sterilization equivalent of "It can't be stuck if it's liquid"
