View attachment 354075I admit, I've not read the whole post, but rather just the OP's question and now rushed to answer. Why you ask? Because I'm in the act now! I know I'll get flamed for this, but F any framers! Boil that sh-tuff! Why? Is it because of toxins? No! Is it because of residues? No! Is it because it makes the cotton sterile? No! It's because it eliminates any funky tastes!!! I use "organic sterile" cotton balls to make my wicks, but the only ones in shop nearby are all whitened with peroxide. Does that fact bother me? No! It's the fact that there's always a funny taste unless I boil it! I use GreatValue Distilled water ($0.88/gal). I add the cotton to the water then apply heat (very important to add cotton before heat to distilled! Don't believe me, YouTube Mythbusters distilled water). Bring to a boil, then let boil for 15 min. Rinse for 5 min then repeat. Final rinse with 1 gal of distilled water. Never a funny taste, never a burnt taste (assuming you wet the wick thoroughly before vaping). People wanna hate on boiling, but that's the only way I get a clean flavor from my juice. Just my opinion, ymmv...
