What Can I Do to Remove Rust from Metal?
Whether it’s on a tool, automobile, or building, rust developing on metal surfaces can be a nuisance. However, there are several techniques that can be used to remove rust from metal. One common method is the application of an acidic solution. This is because acid will dissolve rust.
Why Does this Work?
So, how exactly does acid remove rust from metal? Essentially, the formation of rust indicates that iron or an iron-containing metal has been oxidized through exposure to oxygen and water. The acid then interacts with this oxidized metal to create a salt. This means that both the rust and the metal are dissolved by the acid. But if the acid is at a particular dilution, it will only dissolve the rust, leaving the metal intact. Generally, the acid in an acidic rust remover is diluted to around 30%. Some commonly used acids in rust removers are hydrochloric acid (also called muriatic acid), hydrofluoric acid, oxalic acid, nitric acid, phosphoric acid, and sulfuric acid.
Pros of Using Acid to Remove Rust from Metal
One advantage of acid-based rust removers is that they tend to work quickly. Some acidic rust removers can even remove rust from metal in mere minutes.
- Minimal Scrubbing Required
Another benefit of using acidic rust removers to remove rust from metal is that they often do not require much scrubbing or agitation to work- they’re strong enough that they can readily dissolve rust on their own. This makes the process of removing rust from metal easy and effortless!
Cons of Using Acid to Remove Rust from Metal
- Can be Hazardous to Work With
The primary downside of working with acidic solutions to remove rust from metal is that they can pose dangers to human health: many acids have the ability to damage skin and lung tissue. However, by taking the proper precautions, you will greatly lessen the likelihood of these injuries occurring. Always work in an adequately ventilated area and wear safety glasses, gloves, and protective clothing. Additionally, make sure you dispose of any leftover solution properly.
