Deep cleaning is the complete and routine cleaning process that removes visible dirt, as well as bacteria and germs. The process focuses on frequently touched surfaces and accessible spaces; however, it should also include the regular cleaning of nooks and crannies that may not get frequent use—for example, a bookshelf. When completing a deep clean, the process usually is two-step. Firstly, those cleaning should physically work to remove dirt and organic matter from surfaces. This will then be followed by the use of disinfectant chemicals to kill germs. It’s essential to clean before disinfecting areas because organic matter and dirt can reduce the ability of disinfectants to kill bacteria. As a practice, deep cleaning aims to thoroughly disinfect spaces from bacteria and viruses, like the common cold or flu. This process will also aid in the prevention of spreading infections, like COVID-19.
