This works to remove typical fine grained haze and
surface scratches. It's the car wax approach, literally.

It's called a "skipdr / skip doctor", one current manufacturer is here...

They're on Amazon.

They're useful for similar levels of damage. And provide a more
consistant operation/environment than a newbie human would be
at polishing anything.

But when you need to burn out real scratches or get down into the
polycarb past some manufacturing defect like bubbles, inclusions,
or lensing, you need a real buffing wheel and some practiced skill.
In good hands, a simple cotton wheel and a bit of plastic polish
will handle anything from trivial haze to severe issues.

The operating words are "compounding / polishing / buffing". A disc
is exactly like clearcoat on a car, only thicker. Approach the small
or large problem area. And the more wrecked it is, the more aggressive
initial grit correction and more polishing grades and finishing steps
you need to apply to fix it.
