For all those wondering how I clean them.
It is a little time consuming, but adds a couple weeks to the life of one.
A) Blow out all remaining juice that comes out
b) Run it under hot water for a few seconds
c) insert water into the hole on the battery end at a high pressure using a syringe - repeat 3 times more
d) do a final run under hot water
e) first shake out the excess water, then blow it out with your mouth
f) if you like, use a condom, and a piece of tape to hold it on the carto on the mouth piece end, and place it in the finger of a glove and whip it around your head (Let gravity pull out the excess water this way)
g) give it 24 hours to fully dry and then fill it up.
On average I get about 50-53 drops of juice in it.
Nascar how are you cleaning these? i have given one of mine a hot water shower so to speak but that was not overly effective.
Thanks in advance.
