Clean Inside of Bottles with Rice

I recently discovered this clever trick. Use raw uncooked rice to clean tall or irregularly shaped bottles that have difficult-to-reach areas. Just take the bottle and add a little water, some rice, and a small amount of dish soap/detergent. Then fit the lid, (or just cover with your hand) and give it a good shaking. The rice is hard enough to scrub any residue from the side of the bottle.
