Plastic boards are high-density polyethylene or polypropylene, which is notoriously hard to machine because the tool chips tend to remain attached rather than break off. This means the cut marks are leaving rough chunks of material that is still connected to the surface.
When that "fuzz" appears on your board, simply sand it off with some coarse sandpaper. Its not much different than wood, its a sacrificial surface that gets renewed periodically by shedding layers.
If you dont understand this concept, you suck at engineering. Even a non-technical person should be able to grasp this concept, but I guess /ck/ is for the exceptionally stupid.
Its called sandpaper. And regular maintenance. Understand?
