If water flowing over continents in rivers is what concentrates salt in our ocean, would a planet that has always been covered in water just be freshwater? The water is just sitting there, not eroding through salts.

    There’s also heat exchange so you’ll have deep sea vents where there could be all kinds of caustic stuff and/or minerals.

    So it wouldn’t necessarily be fresh even if that stuff wasn’t saline
