Natural rust remover

I found out lemon juice seems to be an effective rust remover. I had a very rusty pair of needle nosed pliers. They were completely rusted over and were difficult to open.

I took on juice from a bottle of reallemon and poured it into a gallon ziplock bag. I then put the pliers in it so the metal parts were covered in the juice a left it for a day.

Let me just say that most of the rust is gone and the pliers work again. When I opened the bag it had a metallic odor.

Check out the results.
