Rust is an iron oxide, typically reddish-brown oxide formed by the catalytic reaction of iron and oxygen in the presence of water or air moisture. Rust comprises hydrous iron oxides and iron oxide-hydroxide and is commonly associated with refined iron corrosion. But did you know that rust costs a lot in damages worldwide?
The global annual cost of rust or corrosion is estimated to be $2.5 trillion, roughly 3.4% of the global GDP.
What Causes Rust to Form?
Rust is a natural occurrence that occurs when certain metals are exposed to air and water for an extended period of time. Rust has the chemical formula 4Fe + 3O2 = 2Fe2O3. Steel and iron are the only metals that rust. Other metals can be corroded but do not rust. It is a chemical shift that occurs when metal begins to rust.
Everything around us is composed of many substances. Atoms make up these compounds. Atoms can bond together to form new compounds. Atoms can also combine to form chemical compounds. Rust is a chemical substance. The iron atoms combine with the hydrogen and oxygen atoms to create a fusion reaction. H2O is the formula for water. The addition of water causes a chemical reaction. The end consequence is visible as rust.
Iron or steel will not rust if kept completely dry. When moisture is introduced, the oxidation process begins. Because the air we breathe contains moisture, oxidation will proceed even if no water is supplied to the metal. The air has enough hydrogen and oxygen for the atoms to link with the iron. This causes a chemical reaction known as oxidation, often known as rust. (Source: Sciencing)
Ways to Prevent Corrosion
You can take steps to keep rust from forming on your metal surfaces. The first is to keep items such as tools in a dry place. Even if the tools are housed in a toolbox, rust might form. However, because the air’s moisture exposure is reduced, the process is much slower. If you live in a humid climate, you should consider purchasing a dehumidifier. This machine also reduces moisture in the air, lowering the likelihood of rust formation. Bicycles and lawnmowers, which are generally housed outside, can be covered or put indoors.
Products are available to keep dampness from spoiling your equipment and other items. Silica gel packs aid in the drying of the air in tiny spaces such as drawers or toolboxes. Keeping a couple of these packs in your tool chest helps keep your tools from rusting. Also, if goods made of iron or steel get wet, dry them off as soon as possible. This minimizes the oxidation process. Rust can be avoided in this manner. (Source: Sciencing)
What is the Most Effective Rust Remover
Finding rust on your car, equipment, or elsewhere in your home is inconvenient at best and can cause severe damage at worst. Rust is the common name for iron oxide, which can build on metal over time, mainly if there is moisture in the air. Rust, once established, will gradually tear down the metal and cause it to dissolve. The following are the most effective rust remover:
- The best overall: Evapo-Rust, The Original Super Safe Rust Remover
- The best on a budget: Whink Rust Remover
- The best multipurpose: WD-40 Specialist Rust Remover Soak
- The best for household: Iron Out Spray Rust Stain Remover
- The best for heavy-duty: Corroseal Water-Based Rust Converter Metal Primer
