It is very critical to clean before disinfecting. Because cleaning reduces germs and dirt that allows the disinfectant to active and kill the COVID-19 virus. Disinfectant may kill the virus better if the surface has been cleaned with a detergent first. Those containing over 70 percent of alcohol, oxygen bleach and chlorine detergent are suitable for use on the hard surface, for example using on surfaces where any spilt liquid does not soak in. Health organizations recommend that you should use a 1000 ppm bleach to disinfect hard surfaces. 

Routine cleaning 

It is highly recommended that the workplace should be cleaned at least daily. In some situations, more office cleaning may be required. Specifically, if workplaces operate in shifts, you should clean it between shifts. And if equipment is shared among workers, it is essential to clean between uses. However, special attention should be applied to frequently touched subjects such as the door handles, desks, kitchen surfaces, light switches and so on. Surfaces should be cleaned more frequently when being used repeatedly by a large number of people, after any spillage and visibly soiled.
