What Causes Rust on Knives?

You must be suspicious of how rust came out of nowhere, attacked your valuable knives, and suddenly stole their beauty and efficiency. Although steel knife blades are less prone to rust, failure to maintain them properly can make them vulnerable to oxidization and eventually lead to corrosion. Here are some of the negligences responsible for their decay:
  • Exposure to Moisture: After washing, if they are not dried properly, the iron in the steel will react with the oxygen in the air and result in Iron oxide(rust). This will also occur when knives are stored in damp areas.
  • Inappropriate cleaning practices: If the knives, after their contact with food, especially the citrics, are not cleaned properly, your knives will corrode.
  • Harsh Scrubs: If the steel blades are regularly cleaned with harsh metal scrubs, the upper protective layer might gradually degrade and make the inner metal prone to rust. 

Step-by-Step Rust Removal Process

Select a suitable cleaning method

There are various effective options when it comes to corrosion removal; just choose your preferred one from these:

  • Vinegar: Take a large glass or other container full of vinegar. Make sure that it can easily accommodate the size of your blade. Put your knife inside and let it soak in for about 30 minutes.
  • Lemon and salt: Begin by applying the salt on the rust spots and then pour lemon juice all over the blade. Keep your knife covered in this mix for about an hour or two.
  • Baking soda paste: Make a thick paste by blending baking soda with water. Settle this mixture on rust stains and let it sit for approximately 45 minutes to an hour.

Perform Scrubbing

After waiting for the suggested time frame for each method, get a non-abrasive scrubbing pad for getting rust off knives. Be gentle to avoid harming the blade’s surface. If some of the stains are hard to remove, use a soft brush, but only for effective areas.

Clean and Rinse

Sweep away the remaining residues of rust and the removing agent using warm, soapy water. Get a gentle sponge for performing this. Further, rinse the knife under running water to clean it thoroughly.

Dry the knife

Pat it dry using a cloth or paper towel to entirely remove moisture from it. 

Protective layer

Once you clean rust off the stainless steel and are done with the drying process, use food-grade mineral oil to apply a layer of protection to the knife. Do not use excessive lubricant; if the quantity exceeds the required amount, wipe it away with a towel. 

Prevention of Rust Recurrence 

Keep your knives safe from the risk of rust by following a few simple-to-care knife maintenance instructions. Follow these to shield them:
  • Cleanse after every use: No matter how frequently your knives are being used, immediately wash them right after accomplishing your cutting chores. The food residue, especially acidic ingredients like tomatoes and oranges, can rapidly provoke corrosion.
  • Use blade holders: Using blade guards, you can protect the knife's edge while also preventing contact with other utensils- one of the causes of nicks and damage liable for promoting rust. Use our accessories, such as Yakushi™ Premium Knife Holder and Yakushi™Wall-Mounted Knife Holder, to keep them safe.
  • Oil the blade: By occasionally applying a layer of knife-specialized food-grade oil, you can safe the blade from potential reactions with moisture and oxygen.
  • Regular inspection: Rust does not immediately cover the entire blades; the growth is gradual. It begins with small reddish-brownish spots and keeps growing until this process is intervened or reversed. If regular inspection is being practiced to identify the signs of decay, you can restrict its spread as you remove rust from kitchen knives at a very early stage.
  • Store mindfully: Before you keep your knives after washing, make sure they are absolutely dry. The storage area must also be hygienic and dampness-free. 


In the battle against rust, knowledge is your greatest partner. Armed with an understanding of corrosion's causes and the steps to banish it, you can rescue your knives and keep them pristine. Remember, diligent care and maintenance are the keys to preserving both their elegance and cutting precision. With these techniques at your disposal, your culinary journey remains untarnished and sharp.
