Some people with OCPD, but not all of them, have a strong need to be clean. Those that do not show this tendency are sometimes good at setting up systems to keep clean, but may not follow through with the need to clean because of other "more important" things. For example, the need to finish a project at work might cause the OCPD person to have a quite unorganized home. But if that same person was suddenly unemployed or finished with other things, they could very well start becoming more concerned about being clean as they have more free time.
