How do you prevent rust?

Whenever you get iron, water and oxygen together, you get rust. So the best way to prevent it is to keep them apart; that's what paint does, or the spray-on wax and oil coatings that the car protection companies sell. Keep your tools dry; wipe down your bike after a ride; keep the water away and it can't rust.

In this manner, why does rust occur?

Iron oxide is formed when iron and oxygen react in the presence of water or moisture in the air. Iron oxide is very common, because iron reacts easily with oxygen in the air. Rust occurs when iron or its alloys, such as steel, corrode.

What conditions are needed for rust to occur?

Iron and steel rust when they come into contact with water and oxygen. Both water and oxygen are needed for rusting to occur. In the experiment below, the nail does not rust when air or water is not present. Remember that 21 per cent of the air is oxygen.

What increases rusting?

Rust is a chemical reaction that involves the exchange of electrons between atoms; certain chemicals can accelerate rusting by increasing the electrical activity between iron and oxygen. Substances such as salts and acids increase the conductivity of moisture around metal, making rust happen more quickly.
