Thanks for all the positive comments, I'm glad this instructable has been useful. I know many of you have been adding lots more rice than recommended - try it next time with less. It's not the amount of rice (or the size or weight of the rice alternatives suggested) but the centrifugal action of the grains on the glass surface as you swirl it around that cleans your bottle. And you'll have a few more bites of rice for dinner!
