Yes that is fine, I like to get drift wood myself but I have easy access to water. Some sand blast wood as well. They things to look for is it should be dry not green wood and the bark needs to be removed. Then bake it. Make sure it doesn't have soft bits too they make cleaning worse.
Cleaning isn't ass hard as most will make out, a stiff brush soap a good scrubbing and then a spray disinfectant and some time and it i done. No different than any other cleaning.
