How To Remove Rust From Metal

One of the unfortunate realities of metal ownership is that, given the right conditions, some of them will rust. This cannot only be an unsightly flaw in your otherwise useful metal products, but it can also greatly affect the integrity of these items. So, how does rust form and what can we do to remove it?

What is rust? Rust is an iron oxide and is one of the most common types of corrosion. It forms due to an anode metal giving up its electrons when it comes into contact with a liquid conductor of electrons (an electrolyte), oxygen and a cathode (a metallic substance that accepts electrons). During this process, the electrons flow from the anode metal, through the electrolyte and to the cathode, eventually causing the anode metal to fade away (or rust). Add salt to the electrolyte, and the rusting process will occur even faster.

In short, when iron (an anode metal) comes into contact with oxygen and water (an electrolyte), the metal begins to rust away.

How to remove rust? There are a number of ways that you are able to quickly and efficiently remove rust from the surfaces of your metal items, including:

• Using a wire brush or steel wool to scrub the loose rust from the metal's surface. For smaller rust stains, this method may be effective enough in removing the corrosion, but in bigger ones it can remove up to 50% of the imperfection.
• Use a commercial rust remover if you wish, but you must keep in mind that they are highly toxic to humans. If you do decide to use one of these products, ensure that you use it outside in a well-ventilated area and wear the appropriate safety gear (rubber gloves and a mask).
• Use white vinegar. For small metal items, like jewellery and nails, put them in a small bowl of vinegar and let them soak for a few minutes. Once you remove them, dry them with a clean rag. If you notice any more rust, you can put the metal through one more time. For larger metal items, like bikes and chairs, soak a rag in some vinegar and use it to scrub at the surface. Then, soak some steel wool in vinegar and scrub it over the surface too.
• Use baking soda, lemon juice and vinegar for a high power rust-removal solution.

It is always best to try and remove rust as soon as you notice it developing on the surface of your metal items. This is because, if the corrosion is left unattended, it can actually weaken the metal considerably. And, after all, removing rust from metal is not an overly trying task to complete.
