A. Hi Mahapatra,
Although it will be labor intensive, I think polishing with metal polish is the right thing to do. This will also afford the opportunity for 100% inspection, which seems appropriate after damage from flooding whereby some of the parts presumably suffered only superficial damage and others rather severe damage.
Luck & Regards,
