I’m not a scientist either, but from what I remember from reading the manual; rinse aid helps with drying the dishes, makes it so that water don’t stick to them as well. Added dishwasher salt is what helps with lime scale. My dishwasher has a separate salt container, and I then tell the dishwasher how hard my water is and it will add the appropriate amount of salt to the water.
I think you’re talking about lime scale.
I’m pretty sure the afresh just descaled your dishwasher.
Many dishwashers have a dedicated spot for a “rinse aid” like jet dry, and I’m pretty sure that is just a prevention method for this exact problem.
IDK, I’m not a scientist or anything.

Feel free to correct me if I got it backwards.
I couldn’t possibly correct you because I don’t know enough to know what I’m doing myself.
Since neither of us are scientists, we might have to patiently wait for someone to come along who is, that can straighten out facts here.
