Smoke contaminated component

Hi. I just purchased a vintage Marantz 2100 FM tuner (via eBay) and did not think to ask if the previous home/studio was smoke free. I have removed the top and I am letting it breath. Has anyone had success in removing the odors from within the cabinet? The metal cover also smells and I plan to wipe it down with hydrogen peroxide solution. Now I know "buyer beware". Thanks in advance. J.
