I have a gorgeous old roll top desk that I want to restore. It was left behind my whoever owned the house before me, but it was left in a shed where marmots and mice had access to it. It smells very strongly of urine. Before I get too far into the project, I want to know if it's possible to remove/seal in the odor.

I plan on completely taking the desk apart, cleaning, sanding, and re-staining everything, then trying to seal with shellac. Would this work? It's likely going to be 30-40 hours worth of work, so I want to know if I can actually get rid of the urine smell before I put any more hours into it.
