Now that I have a pump (isn't Christmas great?), I'm thinking through how I'll incorporate it into my brewdays. I'm curious to hear details of how various people have implemented a CIP system. As I understand it, in pro breweries, they make use of a high-pressure sprayer to hit the walls of everything with the cleaning solution, getting some mechanical cleaning effect to help loosen up whatever is sticking to the vessel. I'm particularly curious if anyone does this on a homebrew scale, or simply relies on heat and time in contact.
