Hello, I want to ask you how you can wash the cup? Stainless part is clear, but the hardened resin? I'm not sure what it all last? Hardly the dishwasher. It interests me, because with us, and sometimes used the cup poured it :) Thank you for your answer

- Definitely do not use the dishwasher. Sponge and manually wipe gently. Resin should be water resistant, but I would caution during trimming. ;-)
