Dishwasher safe within top rack only, otherwise hand wash in warm soapy water. Should you experience the appearance of "rust" on any stainless steel product, it is more than likely a discoloration or harmless residue left behind from the electro-polishing process. Buff it out with an heavier kitchen scrub brush.

    fantastic cup

    I have had this cup for over 18 months and have used it on my travels overseas. the biggest benefit is how light weight it is, which is such a bonus when travelling and can put your stainless steel water bottle can fit inside the cup when packing in your bag so takes up less room. highly recommend.
