Denatured alcohol on a piece of old bath towel or wash cloth with a little rubbing will help. Check the wheels, too. They get a crud buildup.
I use a drywall sanding pole with a swivel head and put the cloth on instead of sandpaper. 2-3 minutes to wipe your whole layout. You can even sneak it in the tunnel from each end.
