In the right concentration, chlorine bleach will kill just about anything. ********** "oregon: even non-living things such as viruses and prions?" I don't know about prions, but I am pretty sure that it will work on viruses. One way to prevent someone from being to do a DNA typing on a biological sample is to clean up with chlorine bleach. The bleach does more than just kill the sample, it destroys the DNA. No DNA, no life or reproduction.

What about Prions ??????

Bleach will kill just about anything but spores. Spores have to be killed with heat and pressure like when autoclaving medical instruments.

Yes bleach (and some other disinfectants and chemicals) kill spores, viruses and bacteria when used over a certain concentration and with a sufficient contact time. I would presume from this that prions would also be killed since bacterial spores are the most resistant form of microorganism (they have lots of layers and like a hard shell to allow the dormant bacterium to survive harsh conditions and then germinate when conditions are more favourable) and prions are just bits of folded protein.

Yes, it denature the protein.
