Lids - These can be cleaned in the dishwasher if placed on the top rack to avoid excessive heat damage. Water Bottle - although possible we recommend hand washing the cup and bottle bodies to prolong the slip-proof base and avoid heat damage on the colour-coated surface. If you do choose to use a dishwasher keep in mind that any marks on the cup or bottle body that may occur from extra hot washes or the deterioration of the non-slip base are not covered under warranty as hand washing is recommended.
