I came across a rather Interesting tip to remove rust spots from your knives… and all you need is a couple minutes of time and a lemon.
To get rid of the rust spots simply soak them for a few minutes in lemon juice, you can use the concentrated lemon juice that comes in a bottle, or you can literally rub a lemon section on the knife for a minute or so, then just lightly scrub them with a textured dish scrubby and voila, all the annoying rust spots are gone.
