To clean or not to clean...

That is the question!
Personally I prefer my tea with a bit of depth to it so my cup is rarely cleaned. At one clients office I have had to resort to hiding my cup when I leave so the office cleaner doesn't feel compelled to wash it up.

I know when it is time for a scrub when I drink from the cup and do not get the white patch from my lips making contact with the grime.

Cleaning tends to occur every 6 weeks or so!
