We've run into this too. Here are some ways to return it all to normal.
- Check to make sure your water softener is working correctly.
- Use less detergent (you don't have to fill the detergent cups all the way up)
- Make sure the water is hot enough. If your hotwater tank is not hot enough you may need to use the setting on the washer that heats the water (on ours only the "heavy duty" and the "Sanitise" setings heat the water. The others just get whatever water temp is delivered by the hotwater tank.
- Pull out the racks (so they don't rust) and run a rinse load with half a cup of white vinegar in it.
Somebody on here a while back said the repair man told them to run a cycle with "Tang" in the washer. I tried that and can't say it did anything for me....except give me a reason to now have partially used container of Tang in the pantry in case we get an Astronaut guest

I think that is the citric acid..which they think will eat away at the build up. I do believe however, that once the build up is on the glassware, there is nothing that will take it off. We just threw out our glasses and bought new. Nothing we tried would take it off.

we've run into both....etching that works its way into the glass and you cant get rid of it .... I think because it erodes the surface of the glass. The other is just mineral residue that does come off.
In both cases though I think it is the result of too many minerals in the water or too much detergent. One place I read that if you prewash your dishes it leads to it because the detergent needs something to act on and if the dishes are essentially clean to begin with then there is too much detergent. That was not the issue here...we never pre-wash

I don't prewash, we don't have a water softener and maybe the water is not hot enough. Our water heater temp is set just high enough so you won't get burned using only hot water. I will try on a higher setting and see what happens. i will also try the vinegar.
As for the detergent, I use the little packages...maybe they too have too much for my loads....
