WD40 = Water Dispersant (attempt) 40 was originaly, originaly, blended out of fish oils to solve water intrusion into the cable harness couplings to Atlas missiles at Cape Canaveral which was causing so many of the rocket's mis-fires.
Rustoleum also has a fish oil base. It was originaly, originaly, blended to fight rust at sea.
Fish have been fighting back the sea for 500,000,000 years, so they may have something going.
Chloride ions act as a catalyst for rust. So, be sure to flush the heck out of any item that's been exposed to salts. That may mean road salt, for you electricians out East.
