Emptying a soap bottle is a messing challenge! Here is a great tip from AmericasTestKitchen on how using a chopstick helps!
Most cooks like to keep a pump soap dispenser near the kitchen sink for hand washing. But it’s wasteful to discard the last drops of soap that always collect in the bottom of the bottle. Here’s a fast, neat way to get the soap from one bottle to another. Simply insert a long chopstick into the neck of the newer bottle and invert the older bottle on top. The soap will cling to the chopstick and trickle down more readily.
