GC 3 suspected black smudge marks on balls from the ball returns.


I am getting these black smudge marks on my billiard balls . i suspect that they are caused by the ball return system. The black plastic coating might be breaking down. I cleaned the wire tracks and did remove a lot of black crap and thought I had corrected the problem. I did another further cleaning and there were some black residue removed but I still see some really small smudge marks. I was thinking of removing the the tracks and doing another thorough cleaning and possibly coating the tracks with some sort of protectant but have had no experience with this problem.

So any advice out there ?

The table is going on 40 years old so maybe I will need to replace the tracks if they are available.
