Cleaning a Stanley Quencher? Separate the straw, lid and seals
Stanley advises checking the product base for dishwasher instructions. For Quencher cups, separate the lid and straw, clean accessible gasket areas, and dry components fully.
Stanley 1913 tumblers differ by model. Its official FAQ says to check the product base for dishwasher suitability, while Quencher guidance recommends taking apart the lid and washing the straw separately. Not all seals are removable; never force a gasket.
