After each use, rinse the glass shaker and lid in warm water, removing the silicone seal from inside the lid so both can be cleaned thoroughly before drying and storing.
Avoid abrasive sponges or harsh detergents on the copper; a soft cloth is all it needs to stay pure and precise. Both lid and glass bottle are dishwasher safe, but for best results we recommend handwashing, as high temperatures can cause the copper to fade.
