How does rain form on planets covered in water?

I understand rain requires a nucleus for humidity to bond to but if there are no continents spewing dust in the air how would rain form?

Oceans sometimes have minerals in the water that could end up in the air but those minerals come from continents and I hear parts of the ocean that are far from continents don't have a lot of minerals near their surface.

Salt seems to be everywhere in the ocean. I also hear it gets in the air and can be a nucleus for raindrops. Would an ocean world need to use salt as a rain nucleus?

What is the English translation for the Spanish in this cartoon?

Also if you think Speedy is stereotypical remember the same studio made "Yosemite Sam"

I understand rain forms when water sticks to a nucleus, usually dust. But over the ocean rain forms from salt particles. Would that make rain salt water?

I tried looking it up and found a site (1) that says a nucleus is 1/100th the size of the droplet. That sounds to me salt makes up 1% of the droplet. I also read that in order for water to be fresh in needs to have at most 0.5 parts per thousand of salt (2) so salt needs to be 0.05% of water.

That sounds like ocean rain is salty, does that mean you can't count on rain to replenish your water supplies?
