Cleaning removes dirt, dust, crumbs, and germs from surfaces or objects. When you clean, you will likely use soap (or detergent) and water to physically clean off the surfaces and objects. This may not necessarily kill the germs.

Cleaning is the most important and primary aspect of housekeeping. It is a process of removing dirt, dust and grime by using methods such as dusting, shaking, sweeping, mopping, washing or pol- ishing.
