Mineral oil is a popular choice for lubricating and protecting knife blades because it is inexpensive, readily available, and safe to use. Applying mineral oil to your knife is a simple and effective way to prevent rust, corrosion, and other types of damage. However, it’s important to apply the oil correctly to avoid over-application and ensure that it covers the entire blade evenly. In this article, we will go over step-by-step instructions for how to apply mineral oil to your knife, as well as some tips for doing so safely and effectively.

How to Apply Mineral Oil to Knife

Here are the steps to apply mineral oil to a knife:

  • Clean the knife: Make sure that the knife is clean and free of any debris or particles. You can use a soft cloth or a paper towel to wipe the blade clean.
  • Apply the mineral oil: Using a clean cloth, apply a small amount of mineral oil to the blade. Start at the base of the blade and work your way up to the tip.
  • Spread the oil evenly: Use the cloth to spread the mineral oil evenly over the blade. Make sure that the entire blade is covered with a thin layer of oil.
  • Let the oil soak in: Allow the mineral oil to soak into the blade for several minutes. This will help to nourish the metal and protect it from rust and corrosion.
  • Wipe off excess oil: After a few minutes, use a clean cloth to wipe off any excess oil from the blade. Be sure to wipe off all of the oil, as leaving any excess oil on the blade can attract dirt and dust.
  • Store the knife: Once the blade is clean and oiled, store the knife in a dry and cool place. This will help to protect the blade from rust and corrosion.

It’s important to note that you should only use food-grade mineral oil on knives that will come in contact with food. For non-food knives, any type of mineral oil can be used.

Additionally, when applying mineral oil to a knife, you should avoid using too much oil. A little bit goes a long way, and using too much oil can leave the blade feeling greasy and attract dirt and dust. It’s also important to note that mineral oil should be reapplied periodically to keep the blade properly lubricated and protected. The frequency of oiling will depend on how often the knife is used and stored, but a general guideline is to oil the blade every few months. Lastly, always make sure to store mineral oil in a cool, dry place, away from heat sources and direct sunlight, to prevent the oil from going rancid or spoiling.

Safety Tips

Here are some safety tips to keep in mind when applying mineral oil to a knife:

  • Use gloves: Wear gloves to protect your hands from any sharp edges on the knife blade.
  • Work in a well-ventilated area: When applying mineral oil, it’s important to work in a well-ventilated area to avoid inhaling any fumes.
  • Avoid getting oil on your skin: Mineral oil is safe for use on skin, but prolonged exposure can cause irritation. Avoid getting oil on your skin and wash your hands thoroughly after handling it.
  • Store mineral oil properly: Keep mineral oil out of reach of children and pets. Store it in a cool, dry place, away from heat sources and direct sunlight.
  • Use food-grade mineral oil for food knives: If you are applying mineral oil to a knife that will be used for food preparation, make sure to use food-grade mineral oil, which is safe for ingestion.
  • Dispose of used oil properly: Do not pour used mineral oil down the drain. Instead, dispose of it in a sealed container and take it to a recycling center or dispose of it according to local regulations.

By following these safety tips, you can safely and effectively apply mineral oil to your knife to keep it in good condition.


In conclusion, applying mineral oil to your knife is an easy and cost-effective way to protect it from rust and other forms of damage. By following the steps outlined in this article, you can ensure that your knife is properly lubricated and will remain in good condition for years to come. Remember to use food-grade mineral oil for knives used for food preparation, work in a well-ventilated area, and dispose of used oil properly. With these tips in mind, you can confidently apply mineral oil to your knife and keep it functioning at its best.
