I would not have put anything on it.
I have no suggestion at this point. In the future:
I would have made a wet paste of Tide brand laundry soap and washed the inside of drawers and the cabinet lightly, not trying to soak the wood. Let stand outside in the sun for a day (several days if convenient).
A potpourri ball of some type to develop a new scent. I would use cedar chips/shavings in an open mesh bag.

2 coats of waterbased poly on inside but it still smells. Any ideas on getting rid of smell or sealing it in? thanks
