Thanks for the suggestions fellas... I tried the PBW, although i'm not sure if it's it exactly (it's purple powder, but when I asked for it at the Brewery they were clueless?), they gave me some powdered detergent so I assume that's what it is. Anyways, it worked okay, similar to ISO in that it gets it almost 100% clean, but I still have some holes clogged just on the bottom. I'll try some sort of brush as well instead of just the soak and hot water rinse. I notice the same thing on my Evolver Circ... right where the vapour hits that first inverted dome, there is a dime sized area of resin that is impossible to get clean without a pipe cleaner.
Oldie, i'm not really quite sure what you mean, but there is a black rubber retaining ring on the outside of the bottom of the bamboo which the older units didnt have. What i'm referring to is the inside glass part of the bamboo. On the older units (perhaps yours) it's hollow and you can roll up a piece of paper towel and fleece the bamboo. With the newer units, there is a glass type joint or narrowing or whatever, that prevents that. So 2" up from the bottom there is a little glass shelf with a bunch of black spots of ABV that I can't reach. It's the same stuff on the inside of the gong after a while, black abv dust. I do use a coffee grinder and like a very fine grind so perhaps i'm more susceptible to this. As of now, I think filling the bamboo up with ISO is the only way to clean it?
I also just wanted to add to the thread that after having used the Cloud on and off since its release, my VAS has been CURED!!!
