There are several products on the market to remove rust. You can purchase a rust removal kit from Old Roads and Naval Jelly works well on chrome. You will find the serial number on the bottom of the frame or on the rear fork drop-out. If your bike is not one of these brands or you don't know what brand your bike is, you may have a difficult time finding this info. Of course there are always those old-timers or diehards who know just by looking.
Pictures are always helpful.
