Cleaning reusable water bottles is a pain in the ass. Either you end up digging out a long scrub brush and washing it by hand, or you throw it in the dishwasher and risk melting or the inside not actually getting cleaned. The Clean Bottle Square alleviates all of that with the addition of a removal bottom. The top comes off so you can get to the magical hydrating liquid and the bottom comes off (in the same way) so you can clean it out. The ingenuity of the Square doesn’t stop there, though, it’s got a wide handle that makes it easy to carry and the square shape makes sure it never rolls too far from you. Water bottles should have been this clever all along.
