What is it called when you want everything to be clean and in order all the time?

The desire for everything to be clean and in order all the time is often referred to as "obsessive-compulsive disorder" (OCD) when it becomes a debilitating condition. However, in a more general sense, it can also be described as "perfectionism" or having a "neat-freak" tendency. Individuals with these traits may feel anxious or uncomfortable in disorderly environments.
