36. Using Vinegar to Remove Rust:
To get rid of your knives rust spots, some might suggest using vinegar. Many hacks claim that it could solve the problem when you put the knife in a glass of vinegar overnight. However, this method doesn't work! Other ways you could try are to use half of a potato, put baking soda on it then scrub the knife. Apply a little vegetable oil at the end to prevent rust from re-appearing.
