A wiper is provided for cleaning reactor tubes used in an ultraviolet-light reactor. The wiper has a circular opening sufficiently large to resiliently accommodate a reactor tube. A plurality of wipers can be connected to a wiper support to create a wiper assembly. A rod attached to the wiper assembly, or a wiper, can be moved from outside the reactor chamber for mechanically reciprocating the wiper assembly along the length of the reactor tube in the chamber, whereby, the wiper slides along the outer surface of the reactor tube to wipe off at least some of the fouling that may have accumulated on the outer surface of the reactor tube.
