There is no "bad" wick, there is only wick with too little flux on it (either because the manufacturer was cheap or it evaporated). I use a liquid flux, so I just recoat the wick before using - that way it can absorb A LOT more tin than originally and can clean metalized 1mm holes to the point of looking almost like never used!
