Wedo ECO wicks are coreless flatwicks, made from cotton with the addition of fine paper stability threads. Unlike most flatwicks, which usually have three braids, ECO wicks utilise five braids and have 5 stability threads.
ECO wicks are well suited to hard-to wick paraffin candles. They tend to smoke when used in less challenging blends, so are a bit of a wick of last resort, at least in large single-wick candles. In smaller candles, where ECO1-2 can be used, the results can be excellent.
ECO wicks are treated using Wedo's 'C' type chemical treatment.
