i clean my pax with iso. But sometimes i get concerned because i clean it with iso but they is really now way for me to rinse the inside of it with water (the part you stick a pipe cleaner through). I don't want rinse water down there but who knows maybe the thing is completly water tight and i can just put it under the faucet for a few seconds. if this is the case let me know. But i have been afraid to do that. Anyway, so i have just been kinda wiping out what i can and letting the iso dry. This isn't dangourous isn't. I'm not breathing in any iso right? It never tastes like it but i just want to be sure.
It will just evaporate. But I run my pipe cleaner through my pax after a session while its still fairly hot and it comes right out. I don't use the Iso at all except for cleaning the chamber out. Use propylene glycol for the mouth piece and it will work real awesome.
