I learned from Hurricane Andrew down here in Florida from a relatives experience...at least one of the gun mfgs (RUGER) completely restored a 22 auto free of charge that was ruined from salt water intrusion. Dillion rebuilt two of their progressives trashed from the storm...free of charge. Neither company would take money for their services. Also, for rusted hand tools, pliers, wrenches, screw drivers, etc. Get a large brass vibrator and vibrate the tools in corn cob media....except for large rust pits the parts come out looking new.
