ELI5: Salts are constantly added to the ocean through volcanic emissions, runoff from continents, and the weathering of rocks in general, but is there any process that reverses this and removes it?

Yes. Salt can settle out, be captured by organic processes, and (most commonly) become landlocked. In that last one, a part of the ocean recedes or gets cut off from the rest of the ocean. The water evaporates and deposits the salt (which gets buried over time), then the fresh water rains back into the rest of the ocean.
