ABSTRACT:
A device for cleaning an armrest belt of an escalator without interfering with the normal operation of the escalator. The device includes a container and a roller. The roller is in contact with the surface of the armrest belt such that movement of the armrest belt causes the roller to rotate. The roller is formed of an absorbent material so as to absorb cleaning liquid from the container and so as to apply cleaning liquid to the surface of the armrest belt when rotated by the armrest belt. The device further includes structure for cleaning liquid from the armrest belt.
