I think most vapers keep some paper towel nearby. It's messy "hobby" . I clean my connections and blow out my drip tips all the time. (drip tip = mouthpiece). Unless you get a pipe mod that uses clearomizers that all screw together, you'll always run the risk of the mouthpiece slipping. Stuff is just snugged together using O-rings, even for standard cartomizers and drip tips.
