I answered "Rinse, Sanitize, Fill (No disassembly)", because that is what I normally do.
Sometimes if the beer that just kicked was very clear and clean, and I have a beer ready to fill it back up soon I dont even rinse or anything, just pop the top and rack the new beer into it.
Sometimes if the beer was very cruddy, or I noticed some hop particles in a couple pints, I will disconnect everything and soak in Oxy then Starsan. Sometimes I do this anyhow just as due diligence.
But usually its just a rinse with very hot tap water, then fill about 1/4 full with Starsan solution, shake, let some of the starsan leak out the poppets, dump and then rack new beer in.
