ive never used driftwood yet, but i wonder if soaking in a huge rubbermaid and a VERY weak solution of bleach (like less than a capful) and tons of waterchanges would work?
ill be buying driftwood soon too..
or if it can fit in the oven, put it in there with a pan of water and cook it on low for a few hours? sortof like how you bake a real cheesecake! lol hmmm just ideas..
