Cleanliness
Cleanliness is the quality or state of being clean or the practice of keeping oneself or one’s surroundings clean. Cleanliness is a virtue.
Cleanliness means that there is no dirt, no dust, no stains, and no bad smells. The goals of cleanliness are health, beauty, no offensive odor and avoiding the spreading of dirt and contaminants to oneself and others. In the case of glass objects such as windows or windshields, the purpose can also be transparency. Washing is one way of achieving cleanliness, usually with water and often some kind of soap or detergent.
Since the germ theory of disease, it has also now meant no germs and other waste. In industry, certain processes need conditions of exceptional cleanliness which are achieved by working in cleanrooms. A very new idea is that ‘dirt’ may play a useful role in our immune systems. It is estimated that washing hands with soap and water could reduce diarrheal disease-associated deaths by up to 50%. A large percentage of foodborne disease outbreaks are spread by contaminated hands. Appropriate hand washing practices can reduce the risk of foodborne illness and other infections.
