I rinse out my MLT with the hose. Then I collect some of the hot water from my chiller in the MLT and add PBW. I wash the MLT and anything else that needs washing. After my beer gets to the fermenter I rinse out my BK with the hose, then transfer the PBW water from HLT to BK by way of my pump, thus washing the whole line. Wash out the BK with PBW water, fill HLT with rinse water and transfer to BK again. This whole process takes around 15 minutes. I never sanitize these items. They are all pre-boil/hot side.
