As a cooking enthusiast and someone who loves carbon steel knives, dealing with rust can be a real bummer.
But don’t worry, my friends! I have some easy methods to help you eliminate that annoying rust and bring your favorite knife back to life.
Prepare to say goodbye to rust and hello to a shiny, rust-free blade in no time!
5 Ways to Remove Rust From a Carbon Steel Knife:
- Use vinegar: Soak a cloth or paper towel in white vinegar and wrap it around the rusty areas of the knife. Let it sit for a few hours or overnight. The acidity of the vinegar will help dissolve the rust. Scrub gently with a soft brush or sponge, then rinse and dry thoroughly.
- Baking soda paste: Create a paste by combining baking soda with a small quantity of water. Spread the paste onto the rusty areas and allow it to sit for a few hours, giving it time to work magic. Scrub gently with a soft brush or sponge, then rinse and dry the knife completely.
- Lemon juice and salt: Squeeze fresh lemon juice onto the rusted areas and sprinkle a generous amount of salt over them. Let it sit for a few hours. Use a scrub brush or sponge to remove the rust gently, then rinse and dry the knife thoroughly.
- Potato and dish soap: Cut a potato in half and dip the cut side into dish soap. Rub the soapy potato over the rusted areas of the knife, applying gentle pressure. The oxalic acid in the potato, combined with the cleaning properties of the soap, will help remove the rust. Rinse and dry the knife completely.
- Commercial rust remover: If the rust is stubborn and the previous methods don’t yield satisfactory results, you can try a commercial rust remover specifically designed for knives. Follow the instructions provided with the product and ensure thorough rinsing and drying afterwards.
