Thanks Launderess
I knew well about Cascade....as I also have some boxes of the stuff in my stash.
As I know enough about earlier dishwasher, the "historical" aspect....and the wetting action of rinse aids. And so the chemical aspect...
That said, I just thought that whenever in a detergent and or in an actual " final rinse" rinse aid, the sheeting action they do, would have been something that do actually better and aid the shining, and the drying, rather than the rinsing itself meant as operation in which you have residues of wash solution or else removed by water...
So I came to wonder about the name...rinse aid and it's origin...maybe it's because I am used to hear it called "shine maker" and think of it that way from a multilingual mindset, so, that thing that makes stuff shinier ..so I do keep thinking of it like something that just makes more about the shining by avoiding water sitting and make droplets, and so the drying, rather than for the rinse, meant as the process/operation of rinsing actually...it is and was used in rinsing for the most, yes....but the final use it does actually, so it's final goal, do better the drying and the formation of droplets (so make the rinse water fall down and do not make it sit, with the goal to make stuff more shining and brillant)...not an aid for the rinse itself.....
But, it is an aid for water to fall down, so rinse aid, it be meant as " rinse water aid-----> to fall down /or not sit" shortened in just "rinse aid"... But I think you can come to realize it could seem meaning another thing from a "shine enhancer/ maker" term user's point of view...I do hope I am clear...
Interesting is how in different languages certain concepts do changes, and how modern words and phrasing are just a matter of " how you see it".... that has little to do with language roots...as for taking as example german, which is in anglo- derived language with many similitudes in english, rinse aid it is called anyway klarspüler.... Klar: clear, transparent, shine, brillant spüler: cleaner, actually more rather like something act to clean, or belonging inncleaning or purifying....so also a compound or a machine, it also may mean dishwasher...
