I would soak it in penetrating oil for a day or two, then take a brass or fine steel wire 3 or 4 inch wire wheel available at most hardware stores, mount it on a drill or small bench grinder and watch the rust fly off. Make sure you wear a face shield!! There is a different less aggresive procedure for fine or light rust. Contact me for that info.
Water and aluminum foil can remove surface rust on the chrome of a gun. Steel wool can also be used to remove rust. It is advised to never use a oil to remove rust or to clean a gun.

First, you cannot fix the damage already done but you can repair and stop the rust from doing more damage. Take a fine sandpaper or a wire wheel or steel wool and remove all the rust from the gun. After the rust is removed, reblue the gun with a solution made just for this. Ask any gunshop for the solution you need. If the damage is to the point to make the gun unsafe to use as in holes in the barrel or in the firing mechanisms, you may need to replace the effected parts.
