Here's what happened to me recently and thought I'd post it as a "heads-up" with beads and KL.
I use KL in the coolidor and, as everyone says (and I've experienced) it locks in the humidity. If you're Rh is at the right level, this is great. But if you accidentally get the Rh a bit too high, like I recently did, it can be a PITA to get it corrected. As others have noted, you can pop it into the microwave for a bit or use a hair dryer to bring it down.
I decided that, since I had so much KL, just to toss the stuff that I had in there and start with a fresh container of KL. Since I knew my cigars were up around the 71% range for a while, I put the KL in without any spraying with DW just to see where it would settle.
Ended up settling to between 62% and 63% - PERFECT!
Still, just a note to be careful and cautious when spraying beads/KL with DW - it is frustrating and tedious to bring the Rh back down.
