I'm having trouble find quality cleaning supplies for my vape mods. Looking inside there always seems to be a bit of crud in the mouthpiece and the only one I've been able to get has some serious warnings on the solution bottle. A local vape shop suggested alcohol and a pipe cleaner?? Was in the hospital with pneumonia in May which of course the doctors blamed on vaping. Argued with them and eventually they sheepishly came back and said it was a bacterial infection. As an aside, got busted sneaking a vape draw or two in the hospital, but that's a different story for another time. I think it (the pneumonia) may have been caused by the face diapers we've been wearing as I never washed my cotton one. But, it also seems like a good idea to clean out your vape mode. Personally I leave mine in my pocket when walking around and who know what stuff goes down the mouthpiece. Anyway, if any knows of a good cleaning kit let me know or if one of the manufacturers comes up with one it'd would probably be a good idea.
