No, Chilly's Coffee cups are not suitable for cleaning in dishwashers as this can cause damage to the paint and the vacuum. However, you can wash the lid in a dishwasher separately if needed!
We recommend cleaning your coffee cup after each use with hot soapy water, please do not leave the coffee cup to soak for a long period of time. For a very thorough clean please use bicarbonate soda. Whilst Chilly's Coffee Cups are made of high-grade stainless steel which preserves the flavour and freshness of your drinks, if they are not cleaned regularly it can lead to a smell or taste developing.
