I just take the 1/2" barb off the ball valve, wash it and the hose. Then I have a spray bottle of Star-San that I spray into the closed ball valve.
I spary a little Star-San on the ball valve right while I sanitize the barb and hose just before I do the next dump.
It's a darn site cheaper than wasting alcohol and a little tiny bit of Star-San actually is a yeast nutrient.
