Don't know the size jack your dealing with but in the audio/video industry
We used "Jackfield Burnishers"
To keep thousands of patch points noise
free. I'd try a Google
If you can't find the size you need
Buy a few bare plugs and insert
And twist a few times. New plugs are not smoothed by use and are somewhat abrasive.
