I use 100% VG, I am allergic to PG, and yes VG gunks up the wick. From all the reading, it seems that sweet, darker juice or 100% VG will gunk up the wick. For me, the taste when the wick is gunked up is unbearable!
For 17 days of vaping, I have gunked up three EGO-t attys. I disassemble my first atty and the wick was like hard candy. I soaked the wick but it seem to fall apart on the reassembling of the atty.
I am a noob and a lurker, so I only joined the forum for the rewicking pics,lol. The site has been great on info for the re-wicking of the EGO-t atty.
I will have my first rewicking of an EGO-t atty tomorrow if my silica fiber comes in the mail. I thinking about preparing a bunch of wicks and forgoing of cleaning the wicks if they are to be that delicate.
