Generally speaking, the rust on your vehicle's rotors are the result of not using them. "Ring rust" is a special rust pattern on rotors that indicates a brake caliper that is sticking and not making full contact with the rotor surface. While unsightly, rust is not typically problematic for a brake rotor. Brake rotors are made of iron, and so will oxidise regardless of what you do. What keeps this from being a problem is frequent use. Still, if you have rust on your rotors, it is helpful to know how to get rid of it.
