All metals when exposed to weather undergo some corrosive changes because metals have the tendency to react with oxygen to form metallic oxides. Iron is not exception. Materials made of iron react with oxygen in presence of water and form hydrated iron oxides known as rust. All iron alloys are likely to form rust if left open in the air.
Rust makes the metal fragile. Rust becomes a major issue when it attacks machine parts, automotive parts, concrete-covered steel structure of buildings and other useful iron tools. The iron parts get fragmented and loose the power to withstand force. Hence, rust can lead to major loss.
Rust on Household items:
Household things made of iron are also affected by rust and lose their functionality. The things of daily use when form rust, become unusable. Rust makes the surface of the metal brittle and the mass comes out in form of dust from the main metallic structure. It not only weakens the material, but makes the adjacent places dirty and leaves a difficult-to-remove stain on the surface; Rust Stain Remover can be effective to remove such stains.
Clothes, papers etc. when come into contact with rusted surface catch the stain which becomes irremovable. Even if you hold a rusted structure for long, the small particles of rusted metal get transferred to your hand.
Factors behind Rust formation:
The main factors of rust are Oxygen and Water; water with impurity to be precise. It has been observed that rust does not form in presence of dry oxygen and pure water. So the best way to prevent rust is to block the metal from the elements.
The most common method is applying anti-rust coating on the surface. Varnish, emulsions for metal, or any other suitable waterproof material can be used for this purpose. With proper preventive measures the rate of rust formation can be reduced considerably.
Rust Cleaners often give effective result too. Scientifically prepared rust cleaners remove rust stain and prevent further rusting too. Spray based rust cleaners are easy to use at the same time.
