Danmyers...The distilation process used to make alcohol yields about 30 percent water. It boils off and condenses along with the alcohol. So the water is distilled, and you don't need to worry about it.
Cleaning cd lens ?
Is it wise to open the unit and clean the lens? I have a Marantz DV9500 that will not play all cds. I suspect lens is dirty. Besides a q tip what should I use for liquid ?
