Only 1 problem with demijons

I hate cleaning them as the brush is rubbish....Racked 5 and bottled up a further 10.

When cleaning demijons I hammer closed the ring on a large homebrew bottle brush, add warm water and a tiny smidge of washing up liquid to the demijon, pop the 'handle' into a battery drill and awayyyy you go.  You can bend the brush for good contact with the insides, then it's just a case of getting rid of the froth!
