While stationed in the UK I bought a old curio cabinet that smelled to high heaven. I scrubbed it with everything you can think of. Dragged it in and out of the sun. Still if it was closed up it would stink,,,just not as bad. When we packed out I put some bunches of dried flower inside of the cabinet so they wouldn't get crushed. To my surprise when I unpacked the cabinet a few weeks later it didn't stink.
Now if I run into something like that I clean it and then put a bowl full of potpourri in it and close the door for a few weeks.
