This is to settle an argument with my gf. I say they should be stored upside down to prevent dust from accumulating inside them, she says upright because that’s how it should be and your cabinets shouldn’t be dusty to begin with.

i agree with you. sure your cabinets shouldn't be dusty, but how often are the actually wiped down?? i also store upside down just in case there's still water drops in the cup
