How to clean a dirty pocketknife


Q. Dear Gear Guy, I got a pocketknife from my grandfather, and it’s all dirty and rusty. Can you tell me how to clean it, please?

A. Rusty, I love it when Scouts decide to repair old camping gear rather than just throwing it out. I checked in with my friends over at Gerber Legendary Blades to find out exactly how to best fix your knife.

Here’s what you’ll need:

  • Thick rubber gloves
  • Mild dish detergent
  • Soft sponge (or a toothbrush)
  • Soft cloths
  • Nylon pad
  • Household lubricant (WD-40)
  • Household oil (3-in-1)

knife2CLEAN IT: While wearing your rubber gloves, wet a soft cloth with warm water and wipe down both sides of the blade.

knife3Next, scrub the blade with a soapy sponge. To clean serrated blades, use an old toothbrush rather than a sponge. If there’s junk stuck on the blade, pour dish detergent right on the spot and let it sit for a few minutes before scrubbing again. Rinse the blade with warm water and dry with a clean cloth.

knife4REMOVE THE RUST: Spray the blade with a lubricant like WD-40. Be sure to spray all the rusty areas and then let it sit for one minute.

knife5Now scrub the blade with a nylon pad. Rinse the blade. Repeat with the WD-40 for any stubborn rust spots, letting the lubricant soak in for about five minutes before scrubbing.

knife6Once you’ve removed the rust, wash your blade with warm, soapy water. Finally, dry it off and add a few drops of household oil (3-in-1) to the blade.

    There’s a difference between rust and corrosion. If corroded too badly, the knife may be beyond repair. If it just has surface rust, extra-fine wet-n-dry sandpaper will work. CLR does a good job of removing rust.

    You can get clr and dip the knife in it

  13. mav says:

    Use penetrating oil to loosen the blades and then you can use a very fine steel wool or 600 grit wet/dry sandpaper to get the rust off the blades. Keep the blade lightly oiled to keep from rusting in the future.

    you can use naval jelly to clean the blade but it is a very powerful chemical so you have to be careful when using it but its very effective

    use baking soda on a scouring pad then oil.
