All this talk on how are you going to get it clean.... just put in a cup or 2 of dishsoap, fill it up, turn it on and let it sit overnight! If your not sure it's clean from that do it again. I have had my blowoff tube in a 6.5 gallon carboy clogged on a slightly less than 5 gallon batch and I diddn't have to even insert my carboy brush to get ALL that gunk off. That one took 2 applications of dishsoap and a longer soak time. 2 nights instead of one. SCREW scrubbing, fill'er up and forget. I'm not sure how to get the gunk out of the bottom, the rust/sand/etc... to begin with, but once it is out of there I think it is a KILLER idea. I have come to believe that there are alot of people who won't think outside the box. I hope someday they stop being closeminded and think innovatively. Although some of the arguements are valid. I know someone who got a REALLLLLLY old hot water heater and converted it to a fermenter. The tank was glass though. To clean it they just used some powdered cleaner. I wasn't homebrewing at that time (I was 15, but wanted to, LOL!!) so I diddn't pay attention to what it was that they used to clean it, i just know it was powdered something. I was more interested in the hardware and the finished product. (I got a small taste, it was killer, my dad thought it sucked. He also likes Old Milwauke Light.... which begs the question...) Anyhow, I LOVE this idea. I think it is one of the better ones i've seen in a long time. On a side note, I have seen someone that used a tiny hot water heater as the boil pot or whatever it's called, for a Still. They had a ranco controller hooked up to it to keep the temp at whatever it needs to be at to do the job. There's some out of the box thinking. It worked better than any stainless steel pot on a propane burner set up that I could think of.
