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.




One of the most popular brands in the US, Jet Dry, has the ethoxylated alcohol mentioned in the article:

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


Yes I had it backwards. It’s the old “add soap to water to break the surface tension” kids science experiment: https://youtu.be/ho0o7H6dXSU
