I've been having a run recently of my atty's working horribly. I try to clean them regularly, but it only seems to help for about 10 minutes after they dry. They fire brilliantly and the vapor production is perfect, but once I have to drip again they clog to where I can barely drag. I typically need to blow them out again to give them some spark, but it's never quite the same. I have three 501-T's just like that. Would reapplying the spike/wick help this?
