How do you guys sterilize extra large pieces of driftwood that you found by the river/lake? Smaller pieces you can boil, but what about like a large stump, or a long branch?
If you have access to a power washer you could use that. You could wire brush it to get the loose stuff off. I've often thought I could take the long stuff and put it in a steel 55g drum filled w/ water and start a fire under it to get it boiling.
