Thanks for the advice all. I took a teaspoon-sized sip of the slighly
yellowish brew and my stomach is not happy with me. Some cloves and lots
of water settled things down a bit. Evidently I either need to adjust
dosing or get some better distilled water. I haven't seen gastrointestinal
upset linked with CS on any website so far, is there any reason at all to
suspect the CS as the cause?

James, on the COM-100 can it be used to test for "purity" of distilled water
as well as "strength" (ppm or other) of "CS" solution?
Your answer greatly appreciated,
GS

I use a COM-100 EC/TDS/TEMP tester by HM Digital and would recommend this
tester. It works very well and has three different non-linear EC-to-TDS
conversion factors (KCl, 442TM, NaCl) as well as
temp.

Hi Andreas:
What is the conductance tester you are using? I only have experience
with a PWT (which is designed to test pure water).
It really shouldn't be off the chart. Any PWT or TDS meter should be
able to read close to 1000 PPM.
FYI: Rinsing with distilled water won't remove any actual residue in
the glass container.
To ensure total cleanliness:
1. Use a bit of 3% H2O2 in teh glass container, and wipe down
thoroughly with a clean white paper towel. Leave a tiny amount of H2O2
in place for a few minutes before drying.
2. Rinse with distilled water
3. Dry with a clean white paper towel.
4. If you're a stickler for details, rinse once more with a tiny amount
of distilled water (to remove any tiny fibers from the paper towel).
I never use any type of soap product in any container I plan on brewing
CS in.
There are alot of contaminants that may not affect conductivity.
However, distilled water is regulated, and while I don't agree with the
current standards, contamination shouldn't be a great issue.
