The tea stain on the cup?
Because of minerals in the water, tea will form a film that will stain the inside of the cup. When I use Twinings tea, that doesn't happen: if I buy tea from Upton or Ahmad, it occurs. Any idea why?
Answers:
No idea why, but it's easier to clean off glasses than plastic cups. Bleach does the trick to clean the stains off plastic. A good brush gets them off glass.
