I soak my atomizers in really hot water from my coffe maker once a week then blow them out and allow them to dry over night.I have a Joye302 atty that is over two months old and going strong.I killed a DSE801 atty by poking around at it with a toothpick,It sucked anyway it was one of the high bridge ones and it only worked if you drip or refilled your cart every three or four puffs.I beleive the high bridge is what killed my batteries x3 I think when you fill the cart and push it into the atty the high bridge squeezes half the juice out of the packing giving you a few good hits but I think it runs into the battery eventually gumming it up.Some people say soaking atty's in cola helps because of the acid ,probably won't hurt just rinse well and let dry.Vinegar might work but could leave a taste for a while.I always wipe the condensation off of the cart whenever I refill ,prevents getting juice in the mouth Frown
