Well, the concept of anything shiny and glossy is the same in terms of removing scratches. You're really removing a very fine layer so that the scratches don't reflect light. The car body has a layer of clear coat over the color coat so when you use a scratch remover product, it's taking off the clear coat.

Actually what worked for the clear plastic cover for the spedometer (since I accidentally made a deep scratch with my iron ring) is Brasso. Just apply Brasso to microfiber cloth and rub it over the scratch. You'll have to several runs though (don't expect to get it out right away without some effort).

I use Brasso on a lot of things without any problems. It might be easiest to remove the trim from the car to polish it (or you'll risk getting the polish all over the car).


Edit: just remembered the name of another product that's similar to Brasso but specifically for plastics in cars: Meguiar's PlastX.
