I have probably 15 Joye and generic 510 attys that barely produce vapor or don't seem to work at all. I have tried blowing them out and storing them upside down and letting hot water run through them and blowing them out and letting them air dry for days or connecting them to a battery and blowing through them to dry and nothing seems to revive them. What is your favorite method for cleaning and or reviving these things or are they just toast? I can often hear them sizzling a little when I attempt to use one and can see some glow in them when I look in a dark room, but either you get this huge throat bursting hit with no vapor or you get nothing. I know everyone seems to do something different but whats the consensus on letting them drain overnight? The new attys I get seem to work fine for anywhere from 2 weeks to 3 months lol.
