Good or bad idea for rotors?

I've noticed that the drivers side front disc is always dirtier than the other three on the car. When detailing my wheels is there any harm in polishing the discs back to a fine shine with polish? Sure makes the car look sharp when stepping back from it. When cleaning the car I always spend extra time on the wheels, it's one of those grab some beer for Sunday afternoon projects

Bad idea. Most polishes leave something behind (wax, silicone, polymers, etc.) which will glaze both the rotor and pads, killing the braking effort.

All my rotors rust lightly when I wash the car, and they all polish back up after the first time I apply the brakes. Sounds like you might have some sticking pistons in that caliper.

I second this.
