Step-by-Step Process to Remove Rust from Kukri Knife

Step 1: Prepare a Rust-Removal Solution

• Option 1: Use Rust Remover – Follow the label instructions. Most commercial rust removers must be diluted with water.

• Option 2: Use Vinegar or Lemon Juice – These are natural alternatives. Fill a container with vinegar or squeeze fresh lemon juice to submerge the blade.

Step 2: Disassemble the Kukri (If Possible)

If your kukri knife has a detachable handle or metal guard, remove those components carefully. This allows for deeper cleaning and protects the wooden or horn handle.

Step 3: Apply the Rust-Removal Solution

• Soak a sponge in the prepared solution and gently rub the rusted blade areas.

• If using vinegar or lemon juice, submerge the rusty blade for 30 minutes to an hour, depending on rust severity.

Step 4: Scrub the Rust

Use a toothbrush or small cleaning brush to scrub the affected areas gently. This helps remove surface-level corrosion without scratching the blade.

Step 5: Rinse and Dry the Blade

Rinse the kukri blade under clean water and pat it completely dry using a soft cloth. This step is crucial to prevent new rust from forming.

Step 6: Sand and Smoothen

Using fine-grit sandpaper, carefully sand any remaining rust spots. This also helps to restore the kukri’s polish. Avoid aggressive sanding to protect the blade’s structure.

Step 7: Apply Blade Oil

Apply a thin layer of mineral oil or protective lubricant to the entire blade. This helps create a rust-resistant barrier for long-term preservation.

Step 8: Reassemble and Store Properly

Once the kukri is clean and lubricated, reassemble the components. Store the blade in a dry sheath or wrapped in an oiled cloth to prevent moisture buildup. Avoid damp environments or leather scabbards unless treated.

Kukri Knife Rust Prevention Tips

• Wipe the blade after every use, especially in humid or wet environments.

• Store the kukri in a dry area with low humidity.

• Regularly apply blade oil, especially after cutting acidic materials.

• Consider silica gel packs in your kukri storage box to absorb moisture.
