It might be easier to find tung oil than tongue oil.
Someone on the previous speaker polish thread was using Murphy's oil soap. DO NOT use this. A friend is in the hardwood floor refinishing business and he says this product is what provides him with his living. If it is caustic enough to take the finish off hardwood flooring over time. I'd hate to think what it does to speaker cabinets. Murphy's used to be one of my favorite cleaning products. :(
