What Should You Do If Your Kitchen Knife Is Rusted

Rust is one of the most common and frustrating problems that arise with metal.  Rust can occur on any type of metal, but it’s especially common on knives because they’re exposed to acidic foods. The accumulation of rust will eventually lead to a weakening and eventual fracture in the blade, which can be dangerous if you’re using your knife for food preparation.

How to Clean Rust off a Kitchen Knife?

There are several different ways that you can clean rust off a kitchen Huusk Messer. However, it’s important to understand that some methods are better than others, depending on how bad the rust is. Here are a few options to consider:

1. Using a Scouring Pad with Soap and Water

The first step is to examine the blade of the knife and see if it’s rusted or not.  If it’s not rusted, you can use a scouring pad with some soap and water to remove any dirt build-up on the blade.

2. Using Steel Wool and Dish Soap

If it is rusty, then you should begin by using steel wool and dish soap to scrub the rust off of the blade.  This will be a bit more work but can also be very effective. You’ll want to use an abrasive pad or fine-grade steel wool to gently rub away at the rust until it’s gone.

3. Using Oven Cleaner

If the rust is particularly stubborn, you can also use oven cleaner to clean your blade.  Make sure that it’s not aluminum because this will likely lead to more damage than good. Remove any paint on the knife to allow for better penetration of the oven cleaner, and then apply liberally to the rusted areas. You can leave it on for as long as you like, and make sure to rinse it off with warm water when you’re done.

4. Removing the Rust with Nail Polish Remover

If you don’t want to use oven cleaner, another option would be to remove the rust using nail polish remover.  Nail polish remover typically consists of a combination of non-water-soluble types of acetone and forms an emulsion when mixed.  When applied directly to the rust, the acetone will react with and dissolve away at the oxidized metal.

5. Applying Ketchup

Applying ketchup to rusted areas of a knife will help to remove it by using natural acids contained in tomatoes. The acid in tomatoes can also be corrosive, so it’s important to avoid contact with non-rusted areas.  Leave the ketchup on for about 10 to 15 minutes before scrubbing it away with warm water.

6. Applying Vinegar

Vinegar is another common ingredient that is used for removing rust from a knife.  You can use either white or apple cider vinegar and apply it directly to the rusty areas of your blade.  Let this sit for about 10 minutes before you scrub away with warm water.

7. Using Toothpaste

This method is most effective for cleaning rust off of smaller blades.  You’ll want to apply toothpaste directly to the surface of the rusty blade and use an abrasive pad or cloth to scrub it away.  You can also use a bit of baking soda if you don’t have any toothpaste on hand.
