I've had little experience getting smells out of wood furniture, but have had a lot of experience getting weird smells out of old acoustic guitars - which is a real bitch when the smell is from inside the sound hole.
- First take a damp cloth (just damp, not dripping) and scrub every inch of the wood (top and bottom). Smells often stick in dust that works its way into every crevice and nook. Mechanical scrubbing will remove the lion's share of this.
- Next stick the stuff out on a hot summer day in direct sunlight for several hours. Do this several days in a row and make sure that you have different angles of the object in the sun (front/back/top/bottom). The UV rays and heat will both help to kill bacteria, and bacteria can cause/enhance smells.
- Take some baking powder and puff some all over the wood, making sure that it gets into any fine cracks. Let it sit for a day or so, then vacuum it up. This powder can get into nooks and crannies that you can't easily fit your rag and will absorb smells.
- After all of the above I'll take a damp cloth with some vinegar and water and rub it all over the stuff one more time.
- Usually this will dramatically reduce stink . . . but in some persistent cases I'll take a single drop of cedar essential oil and rub it into a non-obvious part of the wood somewhere. This will wear off in a week or so, and usually after this period of time the smell should have largely worn off.
Thanks! This is mostly what I've been doing (chairs out out baking in the sun as I type, for the third day) but includes a few things I haven't tried. The smell is definitely still there, and strong enough that when we set them in the living room overnight, the room smells even after I carry them back outside. But--and maybe this is just wishful sniffing--I think maybe it is at least decreasing a bit.
I think it has been cleaned about as well as I can clean it. It has some fairly ornate carvings so getting into them was difficult. When in doubt, I squirted the cleaning product into those and let it run out and down, several times, then squirted with water and blotted, so as to hopefully get out any particles that might be stuck in the deeper carvings.
I've got an orange cleaning product arriving tomorrow and after I clean with that, I'll try the baking powder bath.
I knew that buying used upholstered items carried this risk, but it never occurred to me that wood might, especially wood that appears clean and generally well-carried for.
