An absolute necessity for smooth operation of a model railway layout is clean tracks. The "Roco-Clean" is an ideal rail cleaning vehicle.All dirt, whether it is dust, rubber abrasions, oil, etc. is reliably removed from the track. The "Roco-Clean" may be run regularly as part of a complete train, so there will always be well cared-for tracks on your layout.The wiper of the Roco-Clean consists of the samematerial as the proven Roco-Rubber. If the pores of the wiper become clogged with use, it is easy to clean the wiper with Roco-Rubber (10002).If the wiper is worn down with use, a reasonably priced replacement wiper is available (40019).
