Well....I just got off the phone with Milwaukee about the probe storage solution question. You would never guess what they said.
The recommendation from Milwaukee is:
"The best way to store the probe is to get a small container and fill it with"regular tap water
", remove the cap and store the probe in the water."
Hard to believe...but true.
This makes things very easy. BTW...he also said to make sure you don't
use distilled or deionized water just regular tap water.
