Proper cleaning of the zerodust styus cleaner

I had spoken w/ music direct at the NYC show about how to properly clean this product. Mine has around 9 mos. of lower than average use.I have purchased dislilled water and original palmolive dish detergent for the job. I assume that I submerse the ZD (gel portion w/o cap) in to the warm(30 sec. in the microwave) distilled water w/ a little palmolive and then common sense tells me to rinse the unit w/ more plain distilled water after soaking in the one w/ the detergent. I am not sure how long to soak the bottom (fluid) part in the dist. water /palmolive however. Can anyone shed any light on my next big cleaning project.
