Does bleach kill viruses?

I'm thinking about using bleach to clean my house.

Bleach is one of few substances used in medical laboratories for disinfection and sterilization of surfaces. A 1:100 to 1:10 bleach dilution is effective in most cases to kill microbes on surfaces. Bleach has been shown to rapidly and effectively inactivate HIV on surfaces.

The answer is no bleach kills germs not viruses they are transported from person to person by sneezing and coughing and not covering your mouth and nose.

Bleach DOES kill viruses. Use it at a 1:10 or even 1:5 dilution with water, leave on surface for 10 minutes, then wipe off. You may want to also wipe your surface with water afterward - bleach can be corrosive to some material like stainless steel. Never ingest bleach!  add a comment

Bleach is an EPA-recognized chemical that can be used to kill viruses. Use 1/4 cup of bleach per gallon of water.

Yes bleach kill spores, viruses and bacteria when used over a certain concentration and with a sufficient contact time. The 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)and prions are just bits of folded proteins
