I have been doing some regular maintenance to my SB. I use the drip method and have to regularly wipe out my atomizer as well as the threads to the SB. Since the SB is a sealed unit, I often times have some liquid on the outside of the SB when taking breaks. I am running off of 6v, so it is essential that I have plenty of liquid, which leads to overfilling when the batteries get weak...Anyhow...I have noticed that it has gotten harder to screw my SB together. I used a napkin to wipe away the grey matter that has been getting in the grooves of the SB. I have been doing a pretty good job of wiping excess liquid away as well as making sure my connections are clean. I do have one concern though: I am unable to access the switch and am unclear how much liquid/corrosion might be taking place. I would love a short video on how to take that piece apart, clean it and put it back together. These are my thoughts. Cheers.
