Excessive cleaning
The most commonly known compulsion in obsessive-compulsive disorder is excessive cleaning. It is a compulsion associated with the obsessive thought of being afraid of contamination, and it is about spending excessive amounts of time to clean every item and object in the house and doing the same thing with clothes and everything they consider to be dirty. It is an exaggerated behaviour that may reach the point of cleaning the credit card after every use or their cellphone whenever someone else touched it.
Everything that comes into contact with something or someone that is not themselves is a potential threat, and they feel the urge to clean them. In most cases, they do so repeatedly and with excessive or exaggerated methods.
