Traveler cars: Clean by frequently flushing with fresh water. Periodically clean
car by squirting a detergent/water solution into center openings. Roll car back
and forth to distribute evenly. Flush bearings with fresh water.
Do not use spray lubricants because ball bearings can skid, not roll. Once car
and track are dry, apply one (1) to two (2) drops of McLube®OneDrop™ball
bearing conditioner to ball contact surfaces of track. Roll car back and forth
through OneDrop conditioner several times to distribute onto bearings. Wipe
remaining OneDrop off track. OneDrop conditioner is preferred, but you can also
use one (1) to two (2) drops of a light machine oil. Too much oil attracts dirt.
Track: Clean with detergent and water.
Important! Exposure to some teak cleaners and other caustic solutions can
result in discoloration of part and is not covered under the Harken warranty.
