We just bought a brand new dishwasher from Ikea, called a Lagan. (https://www.ikea.com/ca/en/p/lagan-built-in-dishwasher-white-80462167/)
But it leaves behind a thin layer of dusty residue on everything.
We use a tablespoon of powered dish washing detergent in both wash compartments. And we use a rinse agent. Nothing really works.
Our water is from a well. We would call it mildly hard.
We have gone back to washing dishes by hand because this is ridiculous.
Does anybody have any suggestions? Thanks.
Edit: By "dusty" I mean "stuck on or baked on powdery substance, that does not feel soapy when wet, the same stuff that coats our pots after we boil water" Hmmm... Yes, this sounds like minerals in our water. Maybe we just need a water softener. Thanks, commenters.
