I have always soaked the teapot in hot water and soda crystals when it's really badly stained. It comes out like magic. This would work for cups, too.
I don't have any porcelain but I put the milk in first anyway, so don't get tea stains in the cups. I hate the look and the taste of tea when the milk is added afterwards. It just tastes of water.
Fruit flies - help needed please.
