If all else fails try going to a wine making store. They sell Bentonite as a clearing agent. I bought some, they are grey granuals, and mixed some with warm water to disolve and then used a tablespoon of that liquid for my P&B shakes. Just a thought to help you out if you can't find the Bentonite in anyother form. And it's really cheap to buy it that way too! Hope this helps you.
