i don't have a pot that big, but i'm soaking it in a bleach solution. will rinse and wiped off with hot water in a few.
EDIT: so the driftwood is soaking now in a fresh bucket of water. i'm gonna let it soak for a few days, and let it absorb some water. and maybe get rid of some of the tannins. i also had to trim off a few of the branches. i stuck it in the tank for maybe 1 min just to see if it'll fit and it was not fitting in.
