No Chilly's Bottles are not suitable for dishwashers.
We recommend cleaning your Chilly's Bottle after each use with hot soapy water. For a very thorough clean please use bicarbonate soda. Whilst Chilly's Bottles are made of high grade stainless steel which preserve the flavour of freshness of your drinks, if Chilly's Bottles are not cleaned it can lead to a smell or taste developing. For this reason regular cleaning is highly recommended. When not using your Chilly's Bottle, we recommend storing without the cap on.
