Is Munchkin Cups dishwasher safe?
Sometimes — with care
Munchkin cups are generally dishwasher safe, but it depends on the specific model and materials.
Why
Many Munchkin cups are made from polypropylene (PP) or other dishwasher-safe plastics, but some have silicone valves or temperature-sensitive components that may warp or degrade in high heat. Always check the bottom of the cup or the product manual for dishwasher-safe symbols.
How to wash it
Place cups on the top rack of the dishwasher, away from the heating element. For cups with straws or valves, hand washing is recommended to preserve the seals and prevent damage.
