How to remove rust from the blade of your knife

Knife with rustWhether you’ve found an old knife in one of your old toolboxes or accidentally left your favorite knife outside in the rain, chances are you have encountered a nasty case of rust. Many old timers considered rust the sign of a knife’s quality, but a rusted knife is also dangerous, useless and downright ugly.

Over the years, people have come up with a wide variety of ways to remove rust from the blade of a knife. Many of these might do the trick for you, but heavier rust might require a few methods.

1) The first thing you want to do is thoroughly clean the blade of your knife because dirt can interfere with the removal of rust. Don’t use water because that’s what mostly made your knife rust. Instead, use some sort of cleaning solution and wipe it down with a cloth.

2) Next, apply another coat of rust remover for knives. Soak a rag in oil and cover the knife with it for a few hours to let the solution get into the rust. You can use nearly any type of oil, including WD-40, kerosene, Vaseline, Autosol and even white vinegar.

3) Remove the blade from the rag and scrub off any rust. Most rust removers come with an abrasive cloth, but you can also use steel wool to get it off.

4) Wipe off any excess dirt and oil with a cloth and your blade should look good as new. If not, repeat the above steps with a different cleaning solution or try one of the alternative methods below.
