Baking Soda. Using baking soda is another way to remove rust from metal. You can make a paste by mixing baking soda and water. Make sure that the solution is pasty enough to adhere to the surface, then spread it onto the metal and let it sit. After the rust is loose, you can scrub it off.
Spread this paste on the rusted metal surfaces, and scrub it off after some time. Apply more paste if it gets too dry, otherwise you may cause scratches on the surface. This is the best natural way to remove rust from car trims, garden tools, patio furniture, and any other metal surfaces.
