Question: best way to sterilize and disinfect an environment during the COVID-19  outbreak

Answer passage (source: Australia):
page_title: Cleaning to prevent the spread of COVID-19
section_headers: Cleaning and disinfection
section_content: Cleaning and disinfecting are two different processes:
Cleaning means physically removing germs, dirt and organic matter from
surfaces.
Disinfecting means using chemicals to kill germs on surfaces. It’s
important to clean before disinfecting because organic matter and dirt can
reduce the ability of disinfectants to kill germs.
A combination of cleaning and disinfection will be most effective in removing
the COVID-19 virus. Cleaning reduces the soil load on the surface, allowing
the disinfectant to work and kill the COVID-19 virus. Disinfectant may not
kill the virus if the surface has not been cleaned with a detergent first.

Reviewer feedback on this answer:

Answer passage (source: Australia):
page_title: Hygiene and cleaning for the health workforce during COVID-19
section_headers: Disinfecting
Bleach solutions
section_content: Disinfect surfaces after cleaning. Disinfectant does not work as well on
soiled or dirty surfaces.
Use a ready-made disinfectant that claims to kill viruses, or prepare a
chlorine-based (bleach) disinfectant. Always follow the instructions on the
label.
While bleach (chlorine) solutions are effective, handling bleach can be
dangerous. Consider using a safer alternative if possible.
If you decide to use bleach solution:

follow the instructions on the label
work in a well-ventilated area
do not use it with other products such as toilet bowl cleaners, acids (including vinegar) or anything containing ammonia
wear gloves when handling or preparing the solution
use protective eye wear to protect against splashes
make up the solution daily
use it mainly on hard, non-porous surfaces — it can damage textiles and metals
use a disposable paper towel or cloth to wipe the surface with the bleach solution

For full instructions, read our COVID-19 environmental cleaning and
disinfection principles fact sheet.

Answer passage (source: Australia):
page_title: Cleaning to prevent the spread of COVID-19
section_headers: How do I clean?
section_content: Use the following steps to clean an environment:

Wear gloves when cleaning. Gloves should be discarded after each clean. If it is necessary to use reusable gloves, gloves should only be used for COVID-19 related cleaning and should not be used for other purposes or shared between workers. Wash reusable gloves with detergent and water after use and leave to dry. Clean hands immediately after removing gloves using soap and water or hand sanitiser.
Thoroughly clean surfaces using detergent and water. Always clean from the cleanest surfaces to the dirtiest surfaces. This stops the transfer of germs to cleaner surfaces and allows you to physically remove and dispose of the largest possible amount of germs.
If you need to use a disinfectant, clean the surface first using detergent then apply a disinfectant or use a combined detergent and disinfectant (see next section). A disinfectant will not kill germs if the surface has not been cleaned first. Apply disinfectant to surfaces using disposable paper towel or a disposable cloth. If non-disposable cloths are used, ensure they are laundered and dried before reusing.
Allow the disinfectant to remain on the surface for the period of time required to kill the virus (contact time) as specified by the manufacturer. If no time is specified, leave for 10 minutes.
