Ablutophobia

' Ablutophobia' (from Latin ablutere 'to wash off") is the persistent, abnormal and unwarranted fear of bathing, washing, or cleaning. This phobia is a situational specific phobia. Ablutophobia tends to be more common in children and females than in males. However, the fear generally dissipates in children as they learn that bathing is not something to be feared.
