Before you can slide out the traverse bars the screw on the end of one needs to be removed but it is held by a c section pin. You need to tap out the pin, remove the screw and slide the bar assembly out. You can then polish the bars with wirewool or if harsher action needed fine emery can be used with care. The tubes also can be cleaned as appropriate. Keep trying then slide the bars back until you are happy with the slide. Did mine today, best of luck.
