One of the worst things that can happen to any leaf is rust.

This is something that all chefs and knife enthusiasts try to avoid, and therefore they always make sure to hand wash their knives after each use.

But for a number of reasons, a blade can end up rusting, and it’s not the owner’s fault at all.

Fortunately, there are a few methods you can use to remove rust from a knife, and we review some of them in this article.

So if there is any corrosion on your knives that you have been trying to get rid of, you have come to the right place.

Read on to learn more.

Why do knives rust?

How To Remove Rust From A Knife

Rust occurs due to oxidation of iron.

This happens when metals come in contact with water for too long.

This is because a mixture of oxygen and iron reacts to moisture and results in a reddish substance on the metal.

The substance is called iron oxide, but is more commonly called rust.

Your knife does not even have to be immersed in water for this to happen, in fact water in the air has been known to cause this reaction.

Therefore, you should not leave or wash your knives in the dishwasher, because apart from the fact that the washing cycle can damage and dent the knives, it is usually the cause of rust to leave them wet for too long, even with stainless steel blades.

The proven methods

If you have rust on your knives for any reason, there is no need to panic.

There are a few things you can do to remove the corrosion from the metal that we dive into in this section.

Method No. 1: Use of baking powder

This is one of the most popular and convenient methods out there, as most households already have baking soda in their pantry.

To do this, first clean your knife.

It is best to avoid water as it was first the cause of rust; Instead, you can use a cleaning solution and a cloth to remove all dirt on the blade.

Then mix a generous amount of baking powder with a little water or lemon juice to create a paste.

Then apply the thick paste to the blade and scrub it with a toothbrush if the rust is not too heavy, but if you have a very rusty blade, you may need to use a non-abrasive sponge or steel wool.

Then all you have to do is wipe the blade clean to remove any excess paste and then add a little mineral oil to lubricate the blade and protect it from rust in the future.

Method # 2: Give your leaves a vinegar bath

If you do not have baking soda, this is a good alternative.

For this method you need white vinegar. Be sure to use only this type, as other vinegar can leave stains on the leaf.

White vinegar contains acetic acid that targets and attacks rust.

Simply pour a little vinegar into a saucepan or saucepan and leave your rusty blade there to soak.

Only leave it for a maximum of 5 minutes, as you risk damaging the knife.

Once you have taken the blade out, just dry the blade.

Method No. 3: WD-40

Then there is the WD-40 method, which has been known to work wonders on old, rusty leaves.

First, spray the blade and rusty areas with a generous spritz of WD-40.

Then use very light sandpaper, we recommend 400 gravel and gently sand the rust off the blade.

Be careful not to touch the edge as it may be dangerous and you may also damage the edge of your blade and affect its sharpness.

After lightly sanding the blade, all you have to do is wipe off the excess WD-40, which should be enough to do so.

Keep in mind, however, that this is not the most sanitary method, and we do not recommend doing this with any knife you use for cooking.

Method No. 4: The natural methods

If you do not have any of the above material available, it may be time to look at some natural methods.

Be aware, however, that these are not the most effective ways to get rid of rust, but they do a decent job as none of these materials are natural.

Using an onion

Onions contain sulfonic acids that can help get rid of rust.

Just saw your blade back and forth in the bulb and the acids will slowly begin to remove the rust.

Use of dirt

Dirt is another great way to remove rust naturally.

Some people recommend sticking the leaf in rich soil about a dozen times to get rid of rust.

This does not work for everyone and it depends on the type of soil found in your area, so keep that in mind if you choose to try this method.

Using a potato

This is one of the best natural remedies for a rusty knife.

This is because potatoes contain oxalic acid, which does a good job of removing rust.

To use this method, all you have to do is stick your rusty blade in a potato and let it stand for a few hours.

Then you have to pull it out and then give it a good wipe with oil and it should make the job done.

Conclusion

If you have been staring at a rusty knife and feel bad, it may be time for you to try one of these methods.

Everyone uses simple items that most people have in their household, and if you do not have them, you can always try the natural methods that use food and other natural resources.

The point is, there are many ways people can get rid of rust on their knives using a variety of materials.

And if you really can not get it out, it may be best for you to get a new knife.

If you think one of these methods works for you and your rusty blade, it may be time for you to try them for yourself!
