Even if you have totally pure, desionised, degazed water, it will never stay 
that way. When you submerge your components, the water comes in contact with 
bare metal parts. Not all of those parts are of the same metal. Some of that 
metal will dissolve in the water, and, while doing so, will produce some 
current, whitch in turn will accelerate the process. Turn the power on and this 
will accelerate 100 folds.
In a few minutes, your inert water will become to conductive.

You need a non-ionic fluid like oils or other organic, non-aquous, fluid.

Alchool could be used, as well as glycerin.
