For unknown reasons it鈥檚 much harder to clean than those plastic one. If u gets lazy and let it dry for more than 30 seconds after using it to measure wet / oily / sugar stuff, it鈥檚 game over. The stain forever stays. I hand wash it and put it on dishwasher, the stain still wouldn鈥檛 come off. Harder to clean than my cast iron and carbon steel wok.
