A device and process for cleaning electrical insulators mourned under a n electrified contact rail parallel to a rail track comprises positioning arm( s) attached to a vehicle that travels on the track and a cleaning station with fixed or moveable fingers. The fingers have attached cleaning tools and engage, operate on, partly rota te around the circumference of the insulator, and disengage, as the vehicle passes by the insulator. The cleaning station can also ride on the contact rail and have moveable vertica l members with cleaning tools attached to L-shaped tool holders that rotate around a portio n of the circumference of the insulator. Cleaning tools include powered rotating, reciprocating, vibrating, oscillating and/or linear brushes, wrap-around cleaning belts, sonic horns, ultrasonic vibrating guns, lasers, pressure washing and/or water jetting nozzles on stationary, rotating or oscillating spray bars and spinning heads using stea m, tap or deionized water, and pneumatic polishing nozzles.
