Is Sippy Cup dishwasher safe?
Sometimes — with care
Sippy cups are often dishwasher safe, but it depends on the specific model and materials.
Why
Many sippy cups are made of polypropylene (PP) plastic, which is generally dishwasher safe on the top rack. However, some cups have silicone valves or spouts that may degrade over time with high heat, and printed designs may fade. Always check the manufacturer's instructions.
How to wash it
Place on the top rack of the dishwasher, away from the heating element. For longer life, hand wash the lid and valve with mild soap.
