Hellos guys
I have a nvonu Simonelli Oscar which is a top machine. In the move from home to the roastery the machine was left standing. since its been here I havent used the wand (why would I use drink espresso and filter all the time) .
I had some guests yesterday, made them both an latte and they kindly told me it tasted rank . It was the milk heated from the wand tainted the drink. now ive spent most of this morning cleaning it and soaking it and it still tastes bad, has anyone any ideas?
Cheers
