"Old car Smell" Help

My buddy had a 63 '300' that had a white vinyl interior. It was gross, gray mold everywhere. He spent an afternoon on it with Tilex and the next day it was sparkling white, not a mold spec in sight but it smelled like the said bathroom for a week. That car was cool: 383, 9.25 rear, Street star rims on wide tires and it was green....brakes sucked ***. finally let a head gasket go.
