Since I got my mini it seems it is always with me, in my pocket, on the end table while I'm watching tube, were ever, but mostly in my hand. Now I will wipe down the outside with a damp soft cloth. The inside is a little harder to do around the battery spring ect. Can I take the bottle out , the battery and atty off and rinse the whole device in soapy water and rinse it or is this not recommend.
