Even stainless steel silverware and cooking knives can eventually show a few spots of rust here and there. This is especially common after they've gone through the dishwasher a few times. Fortunately there's an easy way to lift those rust stains off: a good soak in lemon juice.
Obviously you shouldn't put your knives in the dishwasher. But if it happens for whatever reason, head to the fridge and grab the lemon juice. Pour some of it into a tall glass, and then let the knives soak for a few minutes. The acid in the lemon juice should help to loosen up the rust and make it easier to scrub away.
Granted, this doesn't really reverse the damage, but it does give you your clean knives back. And once they're nice and clean, you can start hand-washing them so they don't develop any new stains. That especially goes for your sharp cooking knives. Have you tried this method? Have a better way to get those rust spots out? Let's hear it in the comments below.
