Covid-19: Best household cleaning products to kill coronavirus

The SARS-CoV-2 which is the virus that causes Covid-19 has been shown to survive on some surfaces for up to 16 hours. The US Centers for Disease Control and Prevention recommends daily disinfection for frequently touched surfaces such as doorknobs, light switches and countertops.
The CDC also recommends the use of detergent or soap and water on dirty surfaces prior to disinfection. If someone in your home is sick with flu-like symptoms, consider regularly disinfecting objects in your home, since SARS-CoV-2 has been shown to survive for 16 hours on plastics.
It is important to let the cleaning solution remain in contact with the surface long enough to kill viruses and other pathogens. The time needed will depend on the chemical. Avoid using different cleaning agents at the same time. Some household chemicals, if mixed, can create dangerous and poisonous gases.
Bleach can be diluted with cold water to make an effective disinfectant against bacteria, fungi and many viruses including coronaviruses. You can typically use one-quarter cup of bleach per 1 gallon of cold water, however its best to follow the directions on the label of your bleach.Once you dilute bleach solution as needed, it should be used within 24 hours, as its disinfecting ability fades with time.
Alcohol in many forms, including rubbing alcohol, can be effective for killing many pathogens. You can dilute alcohol with water (or Aloevera to make hand sanitizer) but be sure to keep an alcohol concentration of around 70 per cent to kill coronaviruses. Many hand sanitizers have a concentration of about 60 per cent alcohol, and Lysol contains about 80%; these are all effective against coronaviruses.
Vinegar, tea tree oil, and other natural products are not recommended for fighting the coronaviruses. A study on influenza virus found that cleaning with a 10 per cent solution of malt vinegar was effective, but few other studies have found vinegar to be able to kill a significant fraction of viruses or other microbes. Tea tree oil may help control the virus that causes cold sores, there is no evidence that it can kill coronaviruses.
