Spotting on certain item

[henene4]

Our DW is performing perfectly, except for the odd bit and this one glass baking dish we own.

So, there is literally no spotting on any other item, everything is clean. Just this one, it always ends up with water spots every single time, no matter how its positioned, where, in which kind of load, or which cycle.

So, is it just the dish, could I do something about it, what do you think?

Does your machine have those built-in water softeners that Europe is famous for?
Do you use rinse aid?
Is the dispenser working properly?

That's a tripple yes. The other glases look ok, with only small spots in places other items have touched them. I'm really thinking it is the dish, but what could cause that single dish to behave differently then?

Glass Spots

I have a set of pots and pans with glass lids that do exactly what your glass dish is doing. Doesn't matter if it's washed in the dishwasher or by hand. The only way I've found to avoid the spots is to hand wash and wipe dry immediately.

What type of glass is your baking dish?  I have a few of the Pyrex storage bowls with silicone lids that are perpetually spotted, no matter the machine, etc. and none of my other glass items do this.

Same here - certain glass lids just don't come out perfect. Like Chris said, drying them by hand helps.

Yeah, handwashing and drying helps, but that's the thing: Handwashing xD
So, sadly, nothing to do about that :/

I seriously have no idea what kind of glass that is. It is about 30 years old, but only in use after our old one shattered due to being placed on a damp surface.
