Hi Benjamin,
Thanks for the great review. You're a man after our own hearts. Nobody wants to be the tea wanker at work so yes, this teapot rocks it.
We're firm believers that this is the best Piao Yi teapot you'll find in the UK so you chose well! Because of the design of Piao Yi teapots, you'll never find one that you can take apart to clean below the mesh - certainly we haven't come across one - but we just rinse it through with washing up liquid and water. Rinse thoroughly to ensure all washing up liquid is gone and leave to dry.
We wouldn't really recommend putting this in the dishwasher as, although it's borosilicate glass, dishwashers can be bumpy places and we wouldn't want you the find the infuser basket broken one day. It's not as tough as a heavy duty drinking glass, for instance, so we'd recommend just washing it through in the sink. As long as you don't let anyone prep their dirty staining lingering coffee (joke) with your teapot you'll find this is enough to clean it and avoid nasties building up in there.
Thanks again for the ace review. We're glad you're loving it. Let us know if you need any more equally awesome tea to prepare in it :)
