Mop up is a term used to describe the process of completing a task or cleaning up after a mess. The term can be broken down into four distinct parts: FINISH, SWAB, ABSORB, and CLEAN. Finishing a task means to complete it in its entirety, while swabbing involves using a mop or cloth to wipe away dirt or liquid. Absorbing is the process of taking in or soaking up a substance, and cleaning is the act of removing dirt or debris from a surface. Together, these four actions form the term mop up, which is used to describe the process of completing a task or cleaning up after a mess.
