How to Get Rust Off a Kitchen Knife


If you don’t take care of your knife on a regular basis, it would eventually gather rust. The good thing is that a rusty knife doesn’t necessarily mean that you need to buy a new one. Most of the time, rust is usually at the surface-level. As such, they do not necessarily compromise the overall integrity of your knife.

There are numbers of ways to address this problem. In case your knives are starting to gather rust, you can always try some of our life hacks.

Shine it with vinegar

  1. Fill a tall glass with white vinegar. Make sure that the glass is tall enough so that you can submerge the entire blade of your knife.
  2. Let it sit for five to ten minutes. The vinegar will naturally remove the rust that coats your knife.
  3. In case there are still remaining rust when you remove the knife, you can use a clean sponge to scrub off the rust. By this time, they are already “soft” enough to be removed with just a simple wipe.
  4. Wipe them with a dry paper towel or cloth.

Citrus Solution

  1. Fill a tall glass or any tall container with warm water and lemon juice. You can begin by stirring an equal proportion of these two. Let your rusty knife sit for 10 minutes.
  2. After soaking, remove the knives from the solution and wipe them with a dry paper towel or cloth.


You can use these methods to remove the rust from your kitchen knives. But you also need to remember that regular knife care is still the best solution to this problem. Always avoid soaking your knives in water for a long period of time. And do not store your knife in damp locations since it would only speed up the rusting process.
