I'm no maniac when it comes to cleaning my machine, but I gave it a good cleaning just now (it was about three weeks ago - sorry Carolyn!) and I was amazed at how much better my shot was immediately after a good backflush + descaling. The pour was thicker, wobblier, darker and tasted a lot thicker than usual. I definitely should clean my machine more often.
So how's everybody's cleaning routine? Daily, weekly, monthly? Poll!
