   There are several easy ways to remove rust using common household items:

   2. Baking Soda: Make a paste of baking soda and water. Apply the paste to the rusted area and let it sit for a few hours. Scrub the rust away with a brush or steel wool. Rinse and dry the item.
   
   3. Lemon or Lime Juice with Salt: Sprinkle salt generously over the rusted area. Squeeze lemon or lime juice over the salt. Let the mixture sit for a few hours. Scrub the rust away with the rind of the fruit or a brush. Rinse and dry the item.
   
   4. Potato and Dish Soap: Cut a potato in half and cover the cut side with dish soap. Use the potato to scrub the rusted area. The oxalic acid in the potato helps to dissolve rust. Rinse and dry the item.
