What the hell is rinse aid anyway

It's a special liquid you put in a compartment in your dishwasher to make it work better. I don't bother; I've tried it and haven't observed any effects.

It really depends on if you have a dishwasher that relies on evap for drying, or an explicit heating element. The latter is becoming more rare as time goes on.

I know a guy who washed his dishes, and he died

I know a guy, who has 20 pans and all dirty, washes no 19 to cook his 2$ stake. what a legand.

You'd think the stakes couldn't get any higher!

Rinse aid is completely unneeded if you properly maintain and use your dishwasher. I never use any, and my dishes are completely spotless. 30 years old dishwasher, super hard water. Specifically, you should: - always fill the salt of the dishwasher's water softener once it's empty. It cannot soften the water if it doesn't get cleaned by the salt. If the water is not softened you will get spots. EDIT: Apparently US fo…

> - always fill the salt. rinse aid is for hard water. restaurants probably tend to not treat the water and the commercial dishwashers they use probably tend to not have a provision for salt. they operate very differently than your residential dishwasher. So yes, completely unneeded if you have soft water. Most dishwashers don't have a provision for salt. Also completely unneeded if you don't mind spots.

I have hard water and a dishwasher with a softener. The plates are dramatically cleaner if there's salt in the softener, no matter what detergent i use.

For everyone confused by this comment: In some countries you might find dishwashers with a sort of built-in water softener: https://en.wikipedia.org/wiki/Dishwasher_salt It's not common in the United States. Some all-in-one detergent packets might contain some amount of dishwasher salt, though.

I'll give you an upvote for that little dive into Wikipedia. For those who haven't already swum as deep, the article on ion exchange resins[0] is also worthwhile. Turns out they are used for reprocessing spent nuclear fuel as well as softening water. Plus a few other things. [0] https://en.m.wikipedia.org/wiki/Ion-exchange_resin

I did bad in high school chemistry, I never could understand this stuff. First, the ion exchange resin beads are washed with Na+ which bind to the beads. Second, the hard water is run through the beads and bad stuff like Mg2+ has a stronger attraction to the beads than Na+, so the Na+ is pushed off and Mg2+ binds to beads. The resulting water out of tap is softer because Mg2+ is out, but saltier because Na+ is in. Then once in a while the beads are flushed with Na+ again with the Mg2+ being sent down the drain... but how does this happen if Na+ has a weaker bond? How can it push the Mg2+ off the beads??

Importantly, when they tested a household dishwasher, they didn't find the same issues: > In contrast, the residual substances on the cups washed in a household dishwasher with detergent B were not present at sufficiently high concentrations to exert cytotoxicity and impair the epithelial barrier function (see Fig E9).

If you use a rinse aid in your dishwasher I bet you’d find harmful results. Home detergent does contain AES (sulfates) but it gets rinsed pretty well. However if you use rinse aid, the rinse water itself has surfactants (AES, more sulfates), which will remain on the dishware- that’s the whole point actually, so the water beads off.

The rinse aid prevents beading, actually. Beading is what leaves the spots.

I suffered from chronic diarrhea for years which I attributed to Crohn's disease. This seemed obvious since diarrhea is a very common symptom of Crohn's, but its onset had been several years after I was diagnosed and prior to that I had tended more towards the opposite problem (constipation). I was thus always suspicious that the root cause lay elsewhere. After much experimenting I found that if I ran my dishwasher through an extra rinse cycle the diarrhea went away.

I tried many different detergents but never found one which didn't cause problems, so I've just continued to run an extra cycle. My GI doctor didn't really believe me when I told him. I wonder how many people are having their IBS/IBD symptoms exasperated by detergent residue left on their dishes.

It is talking about professional dishwashers like the ones used in restaurants. So if you dine out on a regular basis you're probably getting exposed to this stuff even if you don't use it at home. PS I have no chemical expertise, but the article singles out alcohol ethoxylates as the cause of this damage. And while I don't use rinse aid in my home dishwasher, my Cascade dishwasher pods list "Isotridecanol Ethoxylate…

Many years ago I worked as a skivvy in a hotel kitchen. We never used any detergent for the crockery, it just used extremely hot water. The dishes seemed very clean and they dried very rapidly.

Yep. If the water is hot enough you don't need chemical detergent or sanitizer. But we're talking about water that is almost boiling -- you'd only find dishwashers that hot in a commercial kitchen.

Fill the salt? Configure for water hardness? I've never heard of either of these things before. Certainly not things on my, relatively fancy, dishwasher.

I’ve never seen a dishwasher without this :)

But I think most people here in the Netherlands never set it up correctly and go for “all in 1” tabs. I never do, always set it up correctly. I do feel I need rinse aid to not have that nasty feel to the glasses.
