What does everyone use to do the initial cleaning after racking? You have to get all the stuff stuck on the side and the trub out of the bottom, so do you just add water and scrub and then use the no-rinse or can you use a dish soap at this stage to help get the smell and really stuck on stuff out and then use the no-rinse? I know soap is bad for head retention, but I wondered if it mattered if you used the sanitizer after.
