As far as WD-40, it is a water displacement fluid (WD=water displacement) but it isn't a desiccant. It can help prevent water on your contacts because it is fish oil based and can stick to contacts helping keep water from being on the contacts. I would recommend the dielectric grease over contact cleaner and WD-40.

Do I have to be cautious about using too much dielectric grease on the FF connectors to avoid interfering with connectivity? Or is that a non-issue when the contact surfaces are twisted into place? Will dielectric grease protect connectors from salt water corrosion? Would it be proper application to fill up the sockets with a big dollop of grease so excess squeezes out when they are screwed together, thereby keeping the salt water out? (That was my original plan before I was warned not to.)
I have heard conflicting "shop talk" about this from fishermen who are not electrical engineers.
