I was just talking with my colleagues how it'd be ideal if some sort of bottle washer was ubiquitous in work/public places. I buy freshly pressed orange from a cafe near work. I try to re-use their disposable bottle (you can't provide your own because volume) but there are only so many times I can wash the orange bits out by hand.
Yeah, I mean for one's own bottles. I have a bottle; it was new, I use it for things like milk or orange juice then I need to wash it to fill out with some other consumable liquid, but washing out orange is hard.
