Deodorizing a dashboard?
 

Hi. I just bought a 93 del Sol S. Previous owner was a freaking slob; the interior was filthy and stunk. I gutted the car and dropped off almost all of the interior parts at a detailer. I did not pull the dash as it sounds like it'd be a big pain in the posterior. However, when I sit in the car that has no interior save the dash I still smell the odor. I assume the dash vinyl has absorbed it. '

Any suggestions on ways to clean and deodorize a dashboard? Thanks!
