Rainwater would disperse the salt water/residue - maybe that's a good thing.
Winch covers could retain salty moisture under them unless the winches are thoroughly dried out before putting the covers on - maybe that's not such a good thing.
I've never had winch covers and I've also never had a problem with winches - maybe that's just a coincidence.
