I rinse and run a hot Oxyclean solution through my pump and all of my hoses at the end of my brewing session. I briefly rinse this same equipment with cold water prior to using it. It will have very hot wort running through it when in use and I rely on that for sanitizing. The only exception to this is the single hose that goes from the chiller directly to the fermenters after cooling the wort. I clean it along with the others as usual, but I keep it submerged in a bucket of StarSan until I'm ready to fill the fermenters. IMO, the key is to rinse ALL of your wort carrying equipment very well with hot water immediately after use followed by the Oxyclean step and another good rinse. I don't use sanitizer on this equipment as it is all pre-boil or pre-hot wort. I save the sanitizer for post boil equipment like fermenters, racking canes, tubing etc.
