If there’s any kitchen utensil that is mistreated and overlooked, it’s your kitchen knife. And being the best lawbreaker myself, I can tell you how kitchen knives often rust over before time.

Also, I will show you how to remove rust from knives with a homemade rust remover. So, when you throw your kitchen knives into the drawer without wiping them off or soaking the water, it starts catching corrosion.

Not only this when you are in a rush and forget to clean the food remnants, but the debris also starts building up.

And it certainly instigates the corrosion. Now that you are here and hoping to restore the novelty of your kitchen knives let’s jump into the easiest and most affordable hacks.

Before You Start

There are certain things that you should know before you get into action. Although if you are only concerned about the removing process only then, you can skip this section.

So, as I was saying, in order to have a precise insight about this topic and avoiding mistakes in the near future, few questions need to be answered. For instance, why your kitchen knives rust over, and how to prevent this inconvenience?

Well, first thing first the most plausible reason is the incapability of water resistance in most of the kitchen knives.

You may ask, “even if I have stainless-steel kitchen knives?

Yes! They are undoubtedly durable and work wonders, but they aren’t invincible. Or I can say that they might be stainless but not stain-free.

After a certain period, they will start rusting over, albeit they are less prone to rust. Thus, when you don’t store your knife in a low humidity area, it corrodes.

In order to withstand this situation, consider taking these preemptive measures.

  • Always soak or drain the water from your kitchen knives after washing them
  • Use a washcloth or a kitchen towel to dry the remaining water. The knives shouldn’t have any trace of water
  • Never keep them unwashed or left out in the sink for an extended period. Always wash it just after using
  • Keep them in low humidity where other metal kitchen tools are placed
  • There are several protective coatings available in the market that helps to inhibit rust buildup
  • Apply mineral oils on your kitchen knives. Take cotton pads or soft cloth and few drops of mineral oil. Now smear it all over the blade from heel to the tip. Repeat this budget-friendly low-maintenance hack thrice in a year

So that’s how you can extend the life expectancy of your kitchen knives and prevent rusting.

Removing Rust from Kitchen Knives — Easy and Effective Techniques

Here I will show you how to remove rust from stainless steel knives or any possible knife you have in your kitchen.

Make sure you wade through each technique so that you can determine the ideal one that works best at your convenience.

The Good’ol Vinegar Solution

There’s nothing that vinegar can’t mend. Be it your clothes or kitchen utensils. Even the grossest and oldest stains can be removed by using vinegar.

Similarly, when your kitchen knives rust over, you need some white vinegar to obtain a spotless blade surface.

In order to do this, you have to gather four ingredients: a container, white vinegar, a spoon or measuring cup, and a scrubber of dishwasher sponge.

Now let’s see how to get these into work!

  • Grab the container and fill it with white vinegar. Use as much as you need. the amount of vinegar should be ample as the rusts over your knives are stiff and unruly
  • Now take the rusted knives and drown them inside the vinegar water and let them rest for 5 to 10 minutes. This process is necessary and makes sure you do not skip it because it lets the rust dissolve gradually
  • After some times, bring your sponge or the scrubber and start rubbing the rust away
  • Keep scrubbing in a circular motion until it comes neat and clean

Note: If the rust is very old or the buildup is outrageously thick, you can let it submerge in the vinegar solution overnight. And then, you can do the scrubbing and remove the rust.

So that’s how you will remove rust with vinegar. This is one of the cheapest and most effective homemade rust removers.

Baking Soda

The next is about how to remove rust from knives with baking soda effectively. This is another cheapest and useful hack to wash away all the dirt, grimes, and rust from your kitchen knives.

But baking soda doesn’t work well if the rust is very old. It rather works on new rust stains or thin layers of rusts on your metal knife. Here you have to follow these simple steps:

  • Make a thick paste with baking soda and water. Don’t apply too much water as the paste needs to be dense and consistent.
  • Now as you have the paste start applying it all over the metal blade with gentle strokes. You can use a paintbrush or anything that supports this regard.
  • Mainly focus on the affected regions of your metal blade and spread the paste all over them.
  • Once you are done with the application, it’s time to let it rest for an hour.
  • After a given time, take a wire brush and start scrubbing the rusted areas until it comes off.
  • When you are done, use clean water to rinse it off, and make sure you dry it before storing

The DIY Cleaner — Lemon and Salt

If you don’t have access to vinegar and baking soda, then you can make your own cleaning agent. And nothing compares to lemon and salt when it comes to low-maintenance cleansing.

Here you will have the needed citric acid or the acidity from the lemon and the sodium carbonate from the salt. This duo ideally cleans all the blemished areas in a jiffy.

However, this is not suitable for deep cleanings. It’s rather a quick and cheap hack for decent cleaning of the small rust patches.

Follow these steps:

  • Take a half-cut lemon and squeeze the lemon juice all over the rusted areas
  • Now cover the affected area with some salt. Make sure the layer is thick
  • Allow it to rest for 2 to 3 hours. You will see the rust has started melting gradually, and the layer has turned into a brown color.
  • You can either use a scrubber or the lemon rind to rub all the spots away from the blade. If that doesn’t work, use a wire sponge or steel wool.
  • Once you are done, rinse it off with clean water and wipe off the leftover water before keeping it inside the drawer.

So, these are the three easiest and effective techniques for removing rust from your knives. However, there are few other methods such as using dish wash, salted potatoes, chemical cleaning agents or cleaning solutions, citric acid, etc. these can also be used for the same purpose.
