Cleaning is the process of removing unwanted toxins, bacteria, impurities, or other substances from an object, human, or specified area. The process can occur over a wide variety of contexts, ranging from commercial cleaning, to personal hygiene, to environmental remediation, to housekeeping. Depending on the context in which the activity is done, there also exist an even wider array of cleaning methods and tools, and it is up to the individual responsible for the task to determine which approach is most appropriate. A hot shower might suffice following a routine workout at the gym, whereas one might use a mop to clean kitchen flooring.
Dry cleaning is a cleaning process that involves the use of a chemical solvent other than water to clean clothing and other textiles. A dry cleaning machine combines a domestic washing machine and a clothes dryer. Dry cleaning is a method used by dry cleaners to clean clothes with specific dry cleaning instructions.
A deep cleaning is performed by a dental hygienist to treat gum and periodontal disease. A deep cleaning cleans between the gums and teeth down to the roots. Tartar buildup is removed down below the gum line to the root of the tooth.
Data cleaning is a process that detects and removes corrupt or inaccurate data points from a record set, table, or database.
