Dirty milk hose at the coffee machine

I have recently a coffee machine and annoy me every day over the dirty milk hose again. Despite being flushed with water after each use, he was totally exhausted after a few weeks. Partly brown discoloration and really no longer appetizing to look at.

There is a really cheap bottle brush at a major online retailer that sounds like a large tropical forest in South America, extremely cheap. This allows me to clean the hose from each side, pull out the milk residue and it looks like new.

I would like to share this tip with you, as I was at first quite baffled and almost desperate and close to the new purchase ... Now I have the hose for almost a year in use and he is still TIPPTOP!
