Exactly why I said "basicly not conductive". In other words it is a crappy enough conductor to not worry about in most situations. Certainly there are better insulators, but as liguids go distilled water is pretty safe until impurities are added (such as by rinsing stuff). So rinse thoroughly and maybe even repeatedly (with fresh clean water) for some situations. Almost anything will conduct electricity under some circumstances. One of the other labs where I used to work (Central Research Laboratories at 3M) spent a LOT of time testing materials under different conditions. What qualifies as an adequate conductor or insulator really does depend on your usage and point of view.
