Rust is the characteristic locution used to call iron hydroxide and iron oxide. Rust one shot forms by iron reacting with O2 when moisture is manifest. Whether you remove either O2 or the moisture, the iron oxidation channels cannot happen and rust cannot be formed. Iron alloys such as steel are again capable of rusting, albeit less so than pure iron. Rusting is a commodious disagreement with many iron objects, thanks to it's bothersome to aim once the evolution has started, and it can causation bent on damage as it corrodes the metal.
Prevention
"Prevention is more fitting than cure." This saying is exceptionally influential in the dispute of rust, now once a plenty of metal starts rusting it's incredibly onerous to site the rusting process. Preventing the rusting process from occurring is especially important if the object in question is near salt water or is exposed to moisture in general. This is because both these factors greatly accelerate the rusting process. If the object is painted and you start seeing small bubbles forming under the paint, you should chip through the paint to check for rust, because these bubbles are usually an early sign of rust developing.
Removal
If you find a rust spot on iron, the most important thing is to remove the rust entirely. Even if you only leave a small speck of rust behind on the iron, the oxidation process can restart very quickly. However, when removing rust you should also be careful not to damage the underlying metal, or you will be facilitating the rusting process. Solvents can be used to remove the rust. You can remove loose rust by scraping it away carefully with a small razor blade. You should also clean the area with warm water and soap after you've scraped away any paint and rust; this ensures that all the rusty debris is gotten rid of.
After the object has dried, you will need to prime the metal and paint over it. The painting over of the exposed metal is the second most important step in preventing a rust spot from growing larger. Exposed iron or steel is more prone to rusting than metal that is covered with paint.
