I suspect the terms are being mixed up here as well. We use DI water for
cleaning in many of the processes in the semiconductor process specifically
because of it's aggressive nature - it's an excellent solvent. But the
generation of DI water is a very expensive process.
For the purposes of amp cooling, distilled water would be just fine and save
you the hassle of mineral deposit accumulation. It will have high volume
resistivity initially but as metals leach from the cooling system the VR
will drop slowly over time.

De-ionized water is NOT pure, it is merely free of ionized atoms or
molecules. There may still be impurities which are not ionized such as
When I worked in the avionics industry, we used de-ionized water to
clean circuit boards. Distilled water was strictly forbidden due to
it's corrosive properties on the plumbing.

### Ok, what do you call rain water, that falls from the sky ?
It was not boiled, but was evaporated. I should collect a sample of rain
water in a SS bowl, then pour into a plastic cap, then stuff the fluke 87
probes into it, and see what the dc resistance is. I did this with tap
and also distilled water. Distilled water was WAY higher, by several
magnitudes. Interesting to note that Paul bought distilled water at
that had low resistance. Caused grief in his vapor cooled alpha. Sounds
to me like they were selling plane tap water....labeled as distilled.
## Folks on here have mentioned the use of distilled AND de-ionized water.
AFAIK, the 4 litre jugs of distilled water, sold at my local grocery store
are distilled only.
