Clean after each use. Although dishwasher safe, we recommend hand washing with mild dish detergent and rinsing and drying thoroughly to prevent the measurement markings from coming off.
We recommend replacing your bottle nipples every two months, or earlier if you spot any signs of weakness or damage. Make sure to check for damage every time you use your bottle, especially if your baby has teeth.
Note: The measurements on the Gen. 3 Glass Baby Bottle and Glass Storage Container bottle bases are printed with food-grade ink. This ink may begin to come off over time if washed with chemical-based detergents, so we recommend washing gently in warm water and sterilizing as normal by boiling in water for 2-3 minutes.
