For those that are tired of scubbing out carboys and kegs by hand here is a fairly cheap solution. I cleaned 9 kegs in 45 minutes and only 2 needed a little elbow grease because they sat too long with yeast in them. I used 170 degree water and it was still hot when I was finished.
There is roughly $65 worth of parts in building this. If you have 5 gallon carboys you may want to replace the spray arm with copper to make it narrower to fit the neck.
