Quoted from jsa:Has anyone had any success restoring the rubber rollers with rubber rejuvinators?
I just took mine out while restoring and honestly just used the same product that cleans up pinball rubbers amazingly--I use Windex Multisurface (buy it at Home Depot). Eats the grease and grime off of rubbers, did the same for these. Mine looked just like yours and came out very nice. Just need to take the lock washers off of one side of the metal frame and slide them off. I soaked mine for 20 mins or so. Most of the gunk from these comes from inside the rollers and and edges where they chafe on the frame. Once that is gone, and cleaned up, you should be good for years.
