I am power washing the deck and I get to thinking to myself "self I have a great idea" "Oh?" I said to myself. Then I thought "this power washer would be a great way to clean the keg I just emptied". Then I thought "self your brilliant", of course I already knew that. So when I finished with my deck I went downstairs and got that keg. I must say that power washer is the way to go. And I didn't use very much water doing it. Unfortunately it would be a bit much to drag my power washer out and set it up every time I empty a keg.
