@GoldieMNI think the main issue I’m having is the soot. Although it isn’t much, it’s not supposed to be there. I have tried 12s, 14s, 18s, 20s and 22s in the cd series. The 18s aren’t completely leaving the jar clean. And i still got soot with the 14s. I am stumped. I might just switch over and try an eco or a premier wick like you suggested. 😊
