Do not know if you are all doing this, but anyway, I wanted to use an old dishwasher as a bottle/keg cleaner,....
The tube inside the bottles:
The cleaned bottle:
This was only a test run with 12 very mouldy bottles. I want to scale it up to 20 bottles, or two kegs.
The test went very well, had the bottles been rinsed after use, they would have now been ready to use. But since they were very mouldy, they could do with a mechanical cleaning and another run.
For the next test I will reduce the lenght of the narrow tubes, and maybe restrict the opening to create a more powerfull jet.
Lesson learned: DO NOT use your kitchen dishwasher for experimentation. For my first test, I blocked one of the caroussels, as I though it would increase the pressure of the other,... it didn't,.... it restricted the water intake and exposed the heating elements which in turn went bright red !
