A wiping board apparatus for cleaning the rectal area of a person following defecation includes a generally planar base that is mountable on a toilet seat. The base is adapted for holding an elongate rail that extends longitudinally in a generally front to back orientation relative to the underlying toilet seat. One or more wiping sheets may be attached to at least one of the base and the rail element for covering the rail element. Following defecation, a user sits on the base and slides over the rail to wipe and clean fecal material from the rectal area.
