What I have done: Put a cork in the bottom, used an eye dropper with the iso into the joint, allowed to drain down till filled to top orifice, then gently turned up/down a little so it flowed in/out of the chamber. Uncorked bottom and allowed to drain out. Repeated with water. Air dried overnight.
That said, as I think more about this and re-read
@Seek's post, I like the idea even less, and I never really liked it in the first place. I've only done this a couple times, and I doubt I'll do it again. Upon reflection, I've never seen enough build-up in the chamber to justify the risk (maybe someone else has had a different experience?). IME at least it really should be sufficient to just use the q-tip/iso above and below the chamber; use water on another couple q-tips to clean out the iso, then air dry. I would never ever turn the unit on while doing this.
@kellya86, while the bamboo is sealed, liquid could enter through the screen around the joint. Yes, if extreme care is used as
@Seek advises, this can be done safely. As I wrote above, I have done it. IMO it is probably unwise unless there is clearly a need. Keep in mind that with normal use only air flows thru that chamber, and the bottom chamber, for that matter. Where you will see build-up is immediately below the joint/ELB.
I should have given more thought before my previous post, which I have now removed. Mea culpa.
Thanks
@Seek for the re-calibration.
