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.
Step-by-Step Instructions. 1  Start by rinsing the area to remove as much rust as possible. ( 2 Don't worry about soap, cleaners, etc and never use harsh chemicals, such as dangerous bleach 3  .). If possible, I recommend soaking the rusted area for at least 30 seconds in the lemon juice or vinegar. Be sure you don't leave any rust behind on metals, as it can spread. 2  For really stubborn rust, you may need to resort to applying a diluted mixture of ammonia (1 tsp per cup of warm water) and allowing the area to soak. 3  Rinse and repeat the steps on how to remove rust if needed.
