I find that it is far easier and less messy to simply take the Humidity Cassette to the sink and soak it, then shake off the surface water & slide it back under the bottom rack. The idea is that the "rocks"slowly release the humidity over an extended period of time, without standing water, which could encourage the growth of nasty things. That said, I live in NYC, and most of the year I have no need to use it, as the humidity in the cellar is OK without it.
