To clean your equipment properly you need 2 bottles of vodka. One cheap, one Stoli. Disassemble equipment, place in bowl of cheap vodka to soak. Take shot of Stoli (maybe several) while waiting. Rinse with water, take shot of Stoli. Pat equipment dry after soaking, take shot of Stoli. Reassemble equipment, take shot of Stoli. Refill equipment, take shot of Stoli. Vape, take shot of Stoli. Drip or refill equipment as necessary to continue vaping, take shot of Stoli. Continue to take shots of Stoli while vaing to prevent vapers toungue. Rinse and repeat.
Works for me!
I have tried an ultrasonic cleaner for both my equipment and for "quick-steeping" liquids, I have seen no benefit to either.
