How do I remove the smell of tobacco from furniture before refinishing?

We recommend the following technique:

1. Spray your project inside and out with Ozium Sanitizer.
2. Place a box or bowl of charcoal briquettes inside your project.
3. Cover your entire project with plastic and let it sit for 24 hours.
4. Clean your project with a Scotch Brite pad and a 50/50 mix of denatured alcohol and water. 
5. Sand the surface with a 150 or 180 grit sanding pad. We recommend Softback Sanding Sponges.
6. If there is still lingering odor, a coat of shellac may help.
