I guess Edmonton has what one would call “hard water”.
I always air dry my dishes. This is for two reasons: why take the time to towel dry them when they can dry while I am doing something else, and I never know how clean my dish towel is. But here in Edmonton, letting them air dry means they are left with mineral deposits making them look spotty and dirty. Even the dishes in the dishwasher come out like that. I have found that opening the door instead of letting them dry by the heat reduces the amount of deposits though.
The same goes for the sinks and tub. I feel bad giving Calvin a bath because the tub always feels dirty. I miss Victoria water, but I suppose this is something I will have to live with.
