Yes, there are several ways to remove rust from metal objects without using harsh chemicals. One method is to use a combination of baking soda and lemon juice to scrub the rust away. Another option is to mix equal parts water and vinegar and rub it on the rusty surface with a soft cloth or sponge. A third method is to make a paste out of baking soda and water and apply it directly to the rusty area. Finally, you can also try using an abrasive material like steel wool or sandpaper to gently remove the rust.
