It's hard to run away from rust. Even stainless steel silverware and cooking knives can show a few spots of rust here and there. And it's common after your silverware gets washed a couple of times. And when rust appears on your utensils, it's not all that pretty. There's an easy way to get rid of it. Just give it a good soak in lemon juice.
Pour some lemon juice into a tall glass, and soak your knives in the lemon juice for a few minutes. The acid in lemon juice should be able to help loosen up the rust making it easier to scrub it off after you pull it out of the glass.
