Ok, so what do I use as a rinse aid then? I just dug all over amazon and pretty much everything has akoxylated alcohol or some form of polyoxypropylene laureth. And yes, I've purposely let the rinse aid run out just to see what happens. It wasn't pretty...
Anyway to make something more "natural"? Some other ingredients I've seen include citric acid, urea, trisodium phosphate. But not sure if just mixing those together would work out....
Plain 5% vinegar will be fine. It will smell funny if you open the door during the dry cycle. But it is safe, non-toxic, and will prevent mineral spots, and help rinse starch.
Install a whole home water filter so you're not washing your dishes in crap water anyways. I don't use rinse aids at all and my dishes come out spotless.
Did you not read what I wrote? Not sure what point you are making... I don't need to brush my hair, wear clothes, or wash my car either... But those are usually considered "proper" things to do. My first load without rinse aid resulted in spotty dishes. Not too bad, but annoying. By the third, it was worse. By the end of the week, all of the glassware was milky white and you could no longer see through it. You know that feeling you get when you run your finger nails across a chalkboard? Yea, we were getting that feeling by just running your hand across a glass plate.
I ended up buying more rinse aid and then running the milky dishes through a cycle with about a 1/4 cup of coffee machine cleaner (citric acid) thrown in.
Our water comes from a local lake and an underground aquifer surrounded in limestone if you are curious.
