[RFI] Tap water is a poor conductor.

[David Robbins]

That white haze would not be fixed by conventional water softeners as all they do is exchange the 'hard' calcium or magnesium ions for sodium... so in effect they changed the calcium carbonate or magnesium carbonate that usually make water 'hard' into sodium carbonate.  The only way to avoid powder residue from anything like that is to use distilled or deionized water.

I agree on the white powder! I worked at a factory that got very hot in the summers. Average days was 120's, a hot august day was in the 130's They installed a mister cooling system where under very high pressure 
1000+ psi water was misted via literally hundreds of nozzles that
created literally a water "FOG" the droplets were sooo fine. They would evaporate literally withing a couple of feet of the nozzle.

Then it was first noticed on dark surfaces the white haze. eventually it was everywhere.

They even tried water softeners and really did not help.

It was a terrible Mess.
