For Bullets with the new IBTS, is there an official recommendation as to cleaning the inside face (IBTS) of the Bullet. The IBTS is said to be self cleaning. On older machines, there is a recommendation to clean the inside every 10kg roasts. I assume that since the IBTS is self cleaning that the every 10kg cleaning recommendation no longer applies.
Is there an official recommendation. It is not clear to me in the updated manual 2.8 .
