I saw a post on here and cannot find it again. I have orange drinking cups and have had couple get clogged. I just replaced them. Someone mentioned cleaning them with Vinegar???? I think... Wondering if I can salvage the clogged cups. The yellow lever that they push to fill the cup is stuck open. Will Vinegar do the trick or is there something else I could soak them in to un-stick them??? Thanks..............
