Seriously. Oil, thicker juices, etc I stick something under the end of the bottle so it pools in the curve close to the top and then come back later to pour it out. Laundry detergent I just leave inverted draining into the cup (and/or rinse several times with water as the washer fills). Hand soap I rinse as I'm making the next bottle of 50/50 mix for a foaming dispenser.
