I have worked in marine research area for years. Several years ago I was involved in a vessel sinking offshore. We had in excess of $200,000 of marine data collection instrumentation on board that went to the bottom. We called in divers and a vessel salvage crew and raised the vessel within 24 hours. When the divers brought up the vessel and gear I quickly opened up all the electronic deck boxes and flushed away the salt water with distilled water then the distilled water with isopropyl alcohol then dried everything as best I could with paper towels and spray cans of air, and a hair dryer. I let everything air dry for a few days. All the equipment still works fine to this day. We lost a few laptops but no data. The laptops were the cheapest thing on board and the data on the hard drives were more valuable. We ripped the hard drives out of the laptops and flushed them the same way. Sent the hard drives to a data recovery service and didn’t lose a single byte of data.

My suggestion is distilled water then isopropyl alcohol then dry as best you can. Spray cans of air to get in all the little crevices.
