How to Remove Rust From Carbon Steel Knife

If you’re like me, you want your knives to last forever. But sometimes, whether it’s from use or storage, rust can form on the blade.

In this blog post, We’ll show you how to use common household items to remove rust from a carbon steel knife in just a few minutes. So if your knife looks a little rough around the edges, keep reading!

How Can a Carbon Steel Knife Get Rust?

First, let’s talk about how rust can form on carbon steel knives. Carbon steel knives are susceptible to rust because they contain iron. When the knife is exposed to oxygen and moisture, it can cause the iron to oxidize and turn into rust.

This is why it’s important to dry your knife properly after washing it and store it in a dry place.

Another way rust can form on carbon steel knives is through acidic or salty foods. Citrus fruits, tomatoes, and other acidic foods can cause the knife to corrode and develop rust spots if not washed and dried immediately after use.

Necessary Tools and Materials

  1. White Vinegar
  2. Lemon or Lime Juice (Can Also Use a Citric Acid Solution)
  3. Aluminum Foil 
  4. Sponge or Scrubbing Brush 
  5. Water 

With these simple household materials, you can remove the rust from your carbon steel knife and bring it back to its shiny, new self.

10 Easy Steps on How to Remove Rust From Carbon Steel Knife

Step 1: Soak the Knife in White Vinegar or Lemon Juice

This method works best for small patches of rust on your knife. Simply soak the knife in white vinegar or lemon juice for about an hour, then scrub off the rust with a scouring pad or brush. Take a small brush and scrub the rust spot until it’s completely removed.

If the rust is stubborn, try soaking the knife overnight in vinegar or lemon juice before scrubbing it off.

Step 2: Use Aluminum Foil & Salt

Scrub the Rust

For larger rust spots, try this method using aluminum foil and salt. Start by tearing off a small piece of aluminum foil and crumpling it into a ball.

Sprinkle some salt onto the rust spot, then use the aluminum foil to scrub the rust in circular motions. The salt acts as an abrasive and helps to remove the rust, while the aluminum foil helps to scrape it off.

Repeat this process until the rust is completely removed.

Step 3: Use Baking Soda & Water Paste

Mix equal parts baking soda and water to create a paste. Apply the paste onto the rust spot and let it sit for about 10 minutes before scrubbing it off with a scouring pad or brush.

This method is great for removing stubborn rust spots, as the baking soda acts as a mild abrasive.

Step 4: Use Potatoes & Table Salt

This method uses the acidity of potatoes to removing rust. Cut a potato in half and sprinkle some table salt onto the cut surface. Then, use the potato to scrub the rust spot in circular motions until it’s removed.

You can also use this method with white vinegar instead of salt for even more rust-removing power.

Step 5: Use WD-40 & a Scouring Pad

Spray some WD-40 onto the rust spot and let it sit for a few minutes before scrubbing with a scouring pad or brush. WD-40 is great for removing rust and also protects against future rust buildup. Try to avoid getting WD-40 on the handle of your knife, as it can make the surface slippery.

Step 6: Use Commercial Rust Remover Solution

Use Commercial Rust Remover

If all else fails, try using a commercial rust remover solution or gel. Simply apply the solution to the rust spot and let it sit according to the product’s instructions before scrubbing it off with a scouring pad or brush.

Step 7: Dry & Oil the Knife

Once you’ve removed all the rust from your knife, it’s important to dry and oil it properly to prevent future rust formation. Use a clean cloth to dry off any excess moisture on the blade, then apply a small amount of mineral oil onto the blade to protect it from moisture.

Be sure to properly store your knife in a dry place when not used.

Step 8: Prevent Rust Formation

In addition to drying and oiling your knife after washing, here are some other tips for preventing rust formation on carbon steel knives:

  • Avoid leaving the knife wet or damp for extended periods of time
  • Avoid cutting acidic or salty foods with the knife
  • Use a knife holder or blade guard to protect the blade when storing
  • Don’t put carbon steel knives in the dishwasher
  • Sharpen your knife regularly to maintain its integrity and prevent rust spots

Step 9: Consider Switching to Stainless Steel

If you consistently struggle with rust on your carbon steel knife, consider switching to a stainless steel knife instead. Stainless steel is more resistant to rust and corrosion, making it a better option for those who don’t want the extra maintenance of caring for a carbon steel knife.

Step 10: Seek Professional Help

If your knife is severely rusted or you’re unsure about how to remove the rust properly, it’s best to seek professional help from a knife sharpener or shop. They will be able to safely and effectively remove the rust and provide advice on preventing future rust formation.
