So in your opinion, soap and water could be enough to clean objects from COVID-19 if you don’t have an alcohol based disinfectant available?
The bleach mentioned in the above article is 5% sodium hypochlorite, which is different from ordinary soap. In everyday life, washing your hands with soap and running water for 30 seconds is sufficient. However, it is not recommended that soaps made for the purpose of being used on human bodies be used on other objects.
