It’s not about how clean the water is, it’s about the mineral content. I don’t know how that is in BC, but here it’s pretty high. That’s one of the reasons if I rinse with water at all I also put it back in iso so I just have to let that evaporate off cleanly rather than letting the water leave minerals behind.
If it was that though, I’d *probably* expect to see water spot shaped deposits where it collected as the water evaporated.
I actually use filtered water in my glass because the water starts leaving a thin coating thats almost unnoticeable at first, then becomes a mix of resin and calcium etc. I think the fact that the head is heated might make the effects of hard water more prominent, since the liquid is quickly evaporated leaving the minerals in a very fast manner, possibly causing the film instead of a slow buildup that starts with spots.
