Completely depends on the environment. If you're in an area of high humidity, and especially where the air has a high salt content because of close proximity to a large saltwater body, it'll happen much quicker than if you were in the desert. Other factors will include, of course, the type of metal used. If the panel which is scratched is made of aluminum, rust isn't an issue. Steel is much more prone to rusting. In short, there isn't a single, all-encompassing answer to your question.

How do you clean rust?

if youre talking about any peice of melt such as a BOLT or anything like that (small) you can use lime juice and rust will come off. let the metal sit in lime juice for a while and then clean off. rust should be gone. if youre talking about a car you should cut or saw peice of metal where car is rusty at and weld in a new peice of metal. simple but will take long.
