Sandpaper to make disc quieter?

[Zepfanman]

Every once and a while, I get a Blu-ray or Ultra HD disc that seems to be unbalanced. I've tried one of the new ones I received yesterday in both of my Ultra HD players, and it makes that terribly distracting whirring noise as it's spinning.

I'm not at home at the moment, but I did hear some advice that you could try leveling the player a little better, so I'll try that. But for the disc itself, is there some kind of trick to make it spin better? Sandpaper the top label perhaps?
