How do you operate the twist and pour stopper?

You turn it half a turn to the right

How do you wash this thermos?

I wash simply with soap and hot water using a bottle brush.

What is the best way to wash this thermos?

Brilliant flask, we use it every night so that we have a morning cuppa. Hot soapy water cleans it but it does get stained, so once a month I use a product called Astonish Cup and Flask Cleaner (available from Amazon) this is powder in a carton which lasts for months and cleans off all stains from anything that is liable to stain.
