How to Get Rust Off of Knives: A Simple Guide

Rust can make knives look bad and dull their sharpness. It also shortens their lifespan. Whether you have small rust spots or big patches, it’s important to get rid of them. In this easy guide, we’ll show you how to remove rust from your knives and bring them back to life.

Why Do Knives Rust?

Rust happens when metal reacts with water and air. This process is called oxidation. Knives that stay wet or are kept in damp places are more likely to rust. Even stainless steel knives can rust, although they are more resistant than others.

Easy Ways to Get Rust Off Your Knives

There are different ways to remove rust. The method you pick will depend on how bad the rust is and what you have on hand. Here are a few ways to try:

1. Baking Soda and Water

One of the easiest ways to remove rust is using baking soda. Baking soda is mild but works well to scrub away rust.

How to Use Baking Soda:

1. Mix equal amounts of baking soda and water to make a paste.
2. Spread the paste on the rusty parts of the knife.
3. Use a soft cloth or sponge to scrub the rust off. Apply gentle pressure.
4. Let the paste sit for about 15 minutes.
5. Rinse the knife with warm water and dry it with a clean cloth.
6. If needed, repeat the process until the rust is gone.

Why This Works: Baking soda is gentle but rough enough to remove rust. It also helps get rid of any bad smells. (Buy now from Amazon)

White vinegar is a great tool for removing rust. The acid in vinegar helps break down the rust and makes it easier to clean.

How to Use White Vinegar:

1. Pour enough white vinegar into a bowl to cover the rusty part of the knife.
2. Let the knife soak in the vinegar for 10 to 15 minutes.
3. After soaking, use a soft brush, like an old toothbrush, to scrub away the rust.
4. Wash the knife with warm water and dry it right away.
5. Repeat the process if necessary.

Why This Works: The acid in vinegar helps dissolve the rust. The longer the knife sits in vinegar, the easier it is to clean. (Buy now from Amazon)

3. Apply the paste to the rusty parts of the knife.
4. Let it sit for 15 to 20 minutes.

4. Steel Wool or Sandpaper

If the rust is tough, steel wool or sandpaper can help. These are rough enough to remove rust but can also damage your knife if used too roughly.

How to Use Steel Wool or Sandpaper:
