I think people have a issue of setting the rinse aid too high. I have soft water and my Bosch is set to the lowest setting. I have never tasted or seen bubbles/residue on my glasses. I think people see the plastics still wet and turn the setting to the max, causing too much rinse aid to be dispensed. Look at a clear drinking glass, if there are streaks, then the rinse aid is set too high. Also I think most DW users add too much detergent, which also clouds/etches the glass making people think the dishes are not clean, so they add more detergent. Everything in moderation, and your dishes will be squeaky clean from a modern DW.

I call shenanigans on the previous poster. Acetic acids and acetic acid salts are chelating agents. Vinegar is a mixture that contains, among other acids, an acetic acid. The acetic acid commonly found in white table vinegar can sequester iron and calcium under acidic conditions. Thank you for your time, Maria

I don't think rinse aid and detergent would work against each other. After all, both contain surfactants and there are some detergents with rinse aid (substitute) available. These rely on an extra-heavy dose of surfactants that are supposed to last through the interim rinse(s) until the final rinse. Here's an current discussion on JD: Alex Here is a link that might be useful: JetDry Solid - 4 Washes and it's almost gone!

It'll take a while. Suction the detergent out with a turkey baster and flush water into it. Repeatedly as needed to get it cleared. Of course, try to not let any of it run down the door and into the machine while doing the flushing.
