Cleanliness is both the abstract state of being clean and free from germs, dirt, trash, or waste, and the habit of achieving and maintaining that state. Cleanliness is often achieved through cleaning. Cleanliness is a good quality, as indicated by the aphorism: "Cleanliness is next to Godliness",^[1] and may be regarded as contributing to other ideals such as 'health' and 'beauty'.

In emphasizing an ongoing procedure or set of habits for the purpose of maintenance and prevention, the concept of cleanliness differs from purity, which is a physical, moral, or ritual state of freedom from pollutants. Whereas purity is usually a quality of an individual or substance, cleanliness has a social dimension, or implies a system of interactions.^[2] "Cleanliness," observed Jacob Burckhardt, "is indispensable to our modern notion of social perfection."^[3] A household or workplace may be said to exhibit cleanliness, but not ordinarily purity; cleanliness also would be a characteristic of the people who maintain cleanness or prevent dirtying.

On a practical level, cleanliness is thus related to hygiene and disease prevention. Washing is one way of achieving physical cleanliness, usually with water and often some kind of soap or detergent. Cleaning procedures are of the utmost importance in many forms of manufacturing.

As an assertion of Moral superiority or respectability, cleanliness has played a role in establishing cultural values in relation to social class, humanitarianism, and cultural imperialism.^[4]

Cleanliness is linked with proper hygiene. A person who is said to be clean usually depicts cleanliness.
