LocksmithTips Remove Rust From Your Keys

Unfortunately, rust is common on keys, but fortunately, it is easy to remove. Your keys take you everywhere, are widely used, and withstand all weather conditions. It is therefore not surprising that your keys will show rust over time. Read on to find out how to remove the rust from your keys to avoid problems easily.

What Is Rust?

We start at the beginning: what is rust? To explain it very briefly, rust is a form of corrosion. Corrosion is a reaction of metal when it comes into contact with oxygen and water. It creates iron oxide and hydroxyl groups, which together form rust. Rust, therefore, attacks the metal, making it porous and vulnerable.

The Effects Of Rust On Your Keys

Rust on your keys can have several consequences. The most important but also the most annoying effect is that rust affects the metal so that it becomes porous. As a result, a key can break off quickly. It is, of course, very annoying in itself, but especially when the key breaks off in the lock. Another consequence is that rust can release. Putting your keys in your jacket or trouser pocket can stain your clothes.

5 Ways To Remove Rust

To prevent rust from corroding and damaging the keys, it is essential to remove rust. By following one of the ways below, you will easily remove all rust from your keys.


Making your keys stainless with vinegar is very easy. Soak the keys overnight in a container of household vinegar and clean with a scouring pad. Repeat this process until all rust has disappeared.

Baking soda

Baking soda is often used as a household cleaner, and it works on your rusted keys too. Make a paste of some baking soda and water, let it soak for a few hours, and then brush it off thoroughly. Tip: An old toothbrush works great for getting between the grooves of the keys.


A well-known trick to remove rust is to soak your keys in a glass of cola overnight. The next day, the rust can easily be wiped off the keys. Cola contains phosphoric acid, which causes the rust to dissolve.


WD-40 is not only a handy lubricant; it is also a panacea for your rusted keys. Spray a coat of WD-40 over your keys, leave it on overnight and remove with a steel sponge the next day. Success guaranteed!

Lime or lemon juice with salt

Like the phosphoric acid in cola, anything that is acidic works well against rust. That is why it is also possible to remove rust from your keys with lemon or lime juice. Sprinkle a little salt over your keys and let them soak in the sap for a few hours (or longer if there is a lot of rust). After this, the rust will be easy to remove.

Prevent Rust On Your Keys

Preventing rust on your keys is, of course, better than a cure. It is the reason we recommend you that regularly check your keys for rust. Also, it is good to keep your keys as dry as possible and remove dirt quickly. That way, you keep your keys clean and robust.
