This info-graphic titled ‘4 Steps to Stop Rust permanently’ provides us an overview of stopping rust forever.
Rust is a natural destructive process observed on steel and iron. It is caused due to the activeness of oxygen and moisture on a metallic surface. Rust is actually the brownish-red oxide formed on the surface of the metal when it comes in direct touch with the atmosphere. Nevertheless, rust takes place not only on iron and steel but also on metallic substances like zinc and aluminum.
Stainless steel does not rust as easily as iron but it is not stain proof. There is a layer of chromium oxide on it which prevents further corrosion, stainless steel cannot be regarded as damage proof. It is necessary to learn a little about rust prevention methods if you want to stop rust on metals. The commonest way to stop rust on metals is by fragmenting or brushing the metallic surface using sandpaper. Another fashionable rust removal method is to apply phosphoric acid, that converts iron oxide into black ferric phosphate on direct application to rusted iron.
