The stainless steel bottle and stainless steel cup parts are top-rack dishwasher safe. However, washing by hand is still recommended, as certain harsher detergents and newer high-temperature dishwashers may affect the appearance of your product. 

All plastic parts are top-rack dishwasher safe.

For best cleaning, separate all parts, including any gaskets, and insert separately into the dishwasher.

Do not scrub with an abrasive brush. 

To clean the underside of cup, cup lid and inside of vessel lid, use of the included small cleaning brush is recommended.
