A handrail treatment device, comprising:

• at least one housing;
• and
• a cylindrical base body rotatably arranged in the housing about an axis of rotation;
• a cleaning facing is arranged on an outer surface of the cylindrical base body over which a circulating handrail of a passenger transport system designed as an escalator or moving walkway can be guided for cleaning,
• wherein at least one radiation source is arranged inside the housing and outside of the cylindrical base body and configured to emit germicidal electromagnetic radiation, wherein the radiation source is exteriorly aligned with the cylindrical base body in such a way that the cleaning facing moving continuously past the radiation source is exposed to the germicidal electromagnetic radiation of this radiation source to clean the cleaning facing when the cylindrical base body rotates.
