We use a barmaid to clean the polycarbonate tanks. Much easier than cleaning by hand. Here is the website: [Only registered users see links. ]
We use the A series, but I'm sure the SS series would work as well. We bought ours from [Only registered users see links. ]., catalog number 929A200 (the barmaid 1-200)model.
Make sure you buy an extra 7.5" brush as the shorter ones don't work as well for cleaning. It isn't very helpful in cleaning AHAB 9 liters but it's sooooo much easier to clean the 1L and 2L.
