Minha contribuição sobre desinfecção (com fontes de alto nivel)
Bleach:
Bleach can be diluted with cold water to make an effective disinfectant against bacteria, fungi and many viruses including coronaviruses. You can typically use ¼ cup of bleach per 1 gallon of cold water – but be sure to follow the directions on the label of your bleach.
Make dilute bleach solution as needed and use it within 24 hours, as its disinfecting ability fades with time.
Non-porous items like plastic toys can be immersed in bleach for 30 seconds. Household surfaces that won’t be damaged by bleach should get 10 or more minutes of exposure.
Bleach solutions are very hard on the skin, and should not be used as a substitute for handwashing and/or hand sanitizer.
Alcohol:
Alcohol in many forms, including rubbing alcohol, can be effective for killing many pathogens. You can dilute alcohol with water (or aloe vera to make hand sanitizer) but be sure to keep an alcohol concentration of around 70% to kill coronaviruses. Many hand sanitizers have a concentration of about 60% alcohol, and Lysol contains about 80%; these are all effective against coronaviruses.
Solutions of 70% alcohol should be left on surfaces for 30 seconds (including cellphones – but check the advice of the phone manufacturer to make sure you don’t void the warranty) to ensure they will kill viruses. Pure (100%) alcohol evaporates too quickly for this purpose.
Containers of 70% alcohol should be sealed to prevent evaporation. But unlike bleach solutions, they will remain potent as long as they are sealed between uses.
A 70% alcohol solution with water will be very harsh on your hands and should not be used as a substitute for handwashing and/or hand sanitizer.
Hydrogen peroxide:
Hydrogen peroxide is typically sold in concentrations of about 3%. It can be used as is, or diluted to 0.5% concentration for effective use against coronaviruses on surfaces. It should be left on surfaces for one minute before wiping.

https://www.rutgers.edu/news/best-ways-kill-coronavirus-your-homeThe effect of H2O2 on adenovirus types 3 and 6, adenoassociated virus type 4, rhinoviruses 1A, 1B, and type 7, myxoviruses, influenza A and B, respiratory syncytial virus, strain Long, and coronavirus strain 229E was studied in vitro, using different H2O2 concentration and timec of exposure. H2O2 in a 3 percent concentration inactivated all the viruses under study within 1--30 min. Coronavirus and influenza viruses were found to be most sensitive. Reoviruses, adenoviruses and adenoassociated virus were relatively stable. H2O2 is a convenient means for virus inactivation.
