How to Remove Rust

Rust corrosion occurs when oxygen reacts with steel and/or iron and moisture is present.

Prolonged contact with liquids, such as water, will cause metals to rust. Metals will also rust if in contact with air with high levels of moisture. If left in a very dry environment, metals won't rust — or at least, it will take a lot longer for them to do so.

Rust corrosion is not only unsightly and uncomfortable to the touch, but also dangerous. It will destroy expensive metal machinery by weakening its structural integrity. Weakened metal will form holes, which can cause fluid leakage and ruin the functionality of various tools and machinery. When metals are weakened, they'll also lose electric conductivity. Metals will also stick to each other if rusted, which makes tools and machinery difficult to handle and use. Additionally, rust can also lower the magnetic properties of metal, which is a problem for complex metal gadgets and other tools that rely on magnetism.

By rusting, metals become useless. If you rely on your metal tools and machinery to perform crucial tasks, rust can be expensive and inconvenient.

However, rust corrosion is also problematic for health reasons, as it heightens the risk of a tetanus infection. Tetanus bacteria are everywhere, but they're especially present on rusty objects. Rust creates rough grooves in which this bacteria can be harbored. Since these grooves are also easier to cut yourself on, you're at a very high risk of infection if you mishandle rusty objects.

After you've successfully removed all rust from your tools, furniture and machinery, prevent rust from forming on them again. Wipe them dry after cleaning them and always store them in dry, non-humid areas. You can also add covers to outdoor furniture to cut down on moisture when not in use.

If you're repainting metal, use rust-resistant primer and rust-resistant paint. Oiling metal surfaces also creates a barrier between the metal and any external moisture.

Rust corrosion is an expensive and dangerous problem. However, most rust problems are easy to solve and prevent. By implementing the above methods, you can prevent threats to your work, finances and health.
