Hey,
Yes, I sold some driftwood on Ebay and I have plenty here in Louisiana. Several years ago I used a water and bleach solution ( HEAVILY DILUTED ) to clean the wood. After doing so I ran the hose over the driftwood for a good five minutes+ soaking every crevice. Then I let it completely dry out in the sun. However, I do not know that this is the BEST procedure, but I have known other herpers that have used this method with success. My python did not show any side effects or illness as a result of applying this bleach, water solution.
Heating the wood in an oven also works according to other local herpers. I do not think you can be too careful about disinfecting the driftwood, so try serveral methods on the same log. Example: try using an extremely diluted bleach and water solution and heavily soak the wood afterwards using plain water. Let the wood dry in the sun. Next, heat it in the oven at 350 for a good 20 - 30 minutes. Keep an eye on the wood
Let me know how it goes!
Good Luck to ya,
ToddG.
