Rust is something that directly affects the performance of a pocket knife. Even a slightly older knife that you didn’t use for some time will rust.

Today, you are going to get informed about some of the most interesting and effective methods to clean your old pocket knife. Most of the pocket knife brands have started using stainless steel in the blades of their knives, but the quality varies.

As a pocket knife lover, you need to be aware of these important things so that you will not have to throw away the old pocket knives from your precious collection.

Air, water, and iron are the major factors that make your iron rust. When your knives are getting too much exposure to any of these, they will rust. Iron is already present in the blade of your knife, which makes rusting inevitable.

We’ll guide you towards the best ways to remove rust from your pocket knife.

How To Remove Rust From A Pocket Knife?

Here are 6 of the most effective ways that can help you remove rust from your pocket knife. By following these natural methods, even your cheap pocket knives will remain functional for years.

Scrubbing Is A Good Idea

Everyone wants to use high-end knives that promise durability and functionality. However, it depends on how you treat your pocket knives. For a nice beginning, trying to remove rust from the knife with simplicity seems a nice idea.

If your knife is not rusted severely, you can simply scrub it and you are done. Use a wire brush, and an old toothbrush, tin foil, steel wool, or sandpaper to scrub off the rust from your pocket knife.

Baking Soda

You must have heard a lot about the cleaning benefits of baking soda. Baking soda has a lot of potential to cut the rust with its chemical formation.

Intelligent housewives know the right use of baking soda, but this is going to be an addition to your knowledge. You can use baking soda for cleaning your pocket knives as well.

Make a paste of baking soda by mixing it in a little water. Make sure it is thick enough to stick and stay on the blade. Leave it like that for some minutes and voila!

White Vinegar For Stubborn Rust

If your pocket knife is dealing with some serious rust issues that have grown stubborn, white vinegar will be on the rescue. White vinegar is acidic, which is why it can easily make rusty things shine again.

People also use white vinegar for cleaning their old jewelry and other ornaments.

Just place your knife on an old cloth and put the vinegar directly on the pocket knife. Wipe it away after a minute or two and dry it. The rust will be long gone by then.

Can Coke Help?

Have you seen people paying shiny new coins everywhere and you just wonder where they get them from? Coke is the answer. Dropping your coins in a glass of cola will instantly make them new, and same is with your pocket knives.

Even the best pocket knives get rusty, but it doesn’t mean you dispose them off. Just leave your pocket knife in a glass of coke. The high phosphoric levels in coke will remove the corrosion and rust in no time.

Easy Peasy Lemon Squeezy

Cleaning your pocket knife with a lemon is probably the easiest way to get rid of the rust. Lemon removes rust by dissolving it. You have to be sure that you don’t leave the juice on your knife for too long to save it from getting damaged. You can also add some vinegar with the lemon juice for guaranteed results.

Consult Mr. Potato

Ever thought that a potato will be the savior of your pocket knife? Well, now it will.

Cut a slice of a potato and add a pinch of salt on it. Rub it over the blade of your pocket knife and wipe it dry. You will see the rust particles getting removed because of the oxalic acid in potatoes.


No matter what method you choose from the above-mentioned ones, be sure you clean and dry your pocket knives properly. If you keep them wet, they will remain vulnerable to get rusty again.

We hope that with these simple and natural methods, removing rust from your pocket knives will not be a daunting task.
