I agree on you on:
that the to-go bottles are not great. The leaking plastic could be improved for sure. I get half-filled bottles then.
I do not agree on you on:
that you can’t get it off your hands. It goes off by time, but you could also use vinegar or better: benzine. 
Just kidding. Peroxide could do the trick. Or just rub a leaf on it or something, it isn’t the end of the world.
