Thank you for viewing. It hasn't been used very often, but there's some water stain or grime on the outside of the pot that won't come off with washing. I've heard it can be removed with citric acid, but I haven't tried it. The pot's diameter is about 22cm and the height is about 18cm. Please use these measurements as a guide, as they are approximate. The inside of the pot is clean, and it comes with a steamer. Thank you.
