Cleanliness
Cleanliness is both the abstract state of being clean and free from germs and dirt, 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”, 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. “Cleanliness,” observed Jacob Burckhardt, “is indispensable to our modern notion of social perfection.” 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.
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.
Cleanliness is linked with proper hygiene. A person who is said to be clean usually depicts cleanliness.
In Islam
There are many verses in the Quran which discuss cleanliness. For example, “…Truly, Allah loves those who turn to Him constantly and He ‘loves those who keep themselves pure and clean” (2:222). And, “…In mosque there are men who love to be clean and pure. Allah loves those who make themselves clean and pure” (9:108).
First lessons in Islamic manuals of catechism are matters of cleanliness. Subjects taught first in the book of cleanliness include: which are clean, what is clean and what is not clean, what people need to be cleansed from, how they should clean, and which water should they use to clean. Muslims are required to perform ablution (wudu) before every prayer, and are recommended to stay in the state of ablution at all times. A ritual bath (ghusl) is performed on Fridays before the Friday Prayer (Juma). Ritual baths are recommended for spiritual purity, also after committing a sin, and are necessary for those who have washed a funeral. Special attention is given to cleaning homes before the arrival of guests or before feasts (Eid al-Fitr and Eid al-Adha), and holy days and nights.
Hygiene
Since the germ theory of disease, cleanliness has come to mean an effort to remove germs and other hazardous materials. A reaction to an excessive desire for a germ-free environment began to occur around 1989, when David Strachan put forth the “hygiene hypothesis” in the British Medical Journal. In essence, this hypothesis holds that environmental microbes play a useful role in developing the immune system; the fewer germs people are exposed to in early childhood, the more likely they are to experience health problems in childhood and as adults.
The valuation of cleanliness, therefore, has a social and cultural dimension beyond the requirements of hygiene for practical purposes.
Industry
In industry, certain processes such as those related to integrated circuit manufacturing, require conditions of exceptional cleanliness which are achieved by working in cleanrooms.
Cleanliness is essential to successful electroplating, since molecular layers of oil can prevent adhesion of the coating. The industry has developed specialized techniques for parts cleaning, as well as tests for cleanliness.
The most commonly used tests rely on the wetting behavior of a clean hydrophilic metal surface. Cleanliness is also important to vacuum systems to reduce outgassing.
Cleanliness is also crucial for semiconductor manufacturing.
