What are the different methods to protect iron articles from rusting ?

$\rm{\purple{\huge{Answer:}}}$

1. Paint it - Paint the metal with any durable acrylic paint. Do not use Water-Soluable paints, since they will only worsen the rust. Rust will form underneath this type of paint.

2. Keep moisture at Bay - Avoid contact with water or moisture. We know that the water has chemical formula which corresponds to 2 parts Hydrogen and 1 part Oxygen. Hence oxygen is responsible for oxidation of iron and therefore forms rust.

3. Coat it with Oil - Use of oil or grease significantly reduces the chances of developing rust in iron. Basically, oil or grease form a protective layer over iron just as paint does and therefore prevent rust formation.
