Does rust spread? If so how does it spreads?

Yes, rust can spread. It occurs when iron or steel reacts with oxygen and moisture, forming iron oxide (rust). Once the rusting process starts, it can continue to spread if the metal remains exposed to air and water, accelerating corrosion. Rust spreads by the continuous oxidation of iron, breaking down the metal’s surface and leading to the formation of more rust. Regular maintenance and protective coatings help prevent or slow down the spread of rust.
