Preventing Rust on Brake Rotors?

Preventing Rust on Brake Rotors?
I wanted inquire to the CL community how the rest of you prevent/get rid of rust on the brake rotors. Both front and back rotors on my '06 IS350 have atrocious amounts of rust on any surface that isn't contacted by the brake pads. Braking speed/bite isn't really affected (at least I don't think so), but the fact that there's so much surface rust is slightly disconcerting.
I read around and saw that my cleaning products may or may not have an effect on the rotors. Right now, I usually wash my wheels with normal soap products (Meguiar's Gold Class) or Meguiar's APC diluted to 10:1. The rust was present when the car was purchased, but I'm not sure if the products I'm using have an exacerbating effect or not.
Does anyone here have suggestions on how I can permanently remove the rust and protect the rotor from future damage? I will post pictures tomorrow to show the conditions of the rotors.
Thanks!

The rust to my knowledge is natural. When rotors come brand new they are coated with something that prevents rusting, once you use the rotors the coating comes off and rotors are supposed to naturally rust until you drive it no?
The brake pad size to rotor can also explain if you have some rust on your rotors, usually this is why rotors need to be re surfaced.
Someone please correct me if Im wrong.

rotors are coated with machine oil to prevent rust. oem has black paint that will eventually rust through. i bought centric premium rotors with an e-coating. it appears to be holding up well. a lot of premium aftermarket rotors like raybestos, etc has this e-coating.

^Over time it'll disappear...like mine did on the PowerSlot rotors. The rears just look awful! Thought about using Metal Rescue rust remover in a bath to remove the current rust; but it'll just come back. Painting will just end up bubbling and cracking at the temps my braking reaches during auto-x/racing.
