Funky Urn?

Funky Urn?


We have a 42 cup hot water urn that we keep on all the time for coffee and tea and such. I made tea yesterday and found that the water from the urn smelled and tasted weird. I know the water stays hot enough that the problem isn't bacteria...maybe mineral build up? Anyway, how do I clean it?

TIA!
