Careful with the vinegar. It might strip the polish. Vinegar gets used as a rust removal agent but IIRC it will attack good metal too if you're not careful. I would be more inclined to use alcohol as long as it was kept away from the machine's finish.
Beautiful machine and cabinet. I do like the cabinet/chair combo units like that and the way they did the chair is just awesome. I think I may have seen that ad. I'm glad it went to a good home. The finish on the machine and cabinet look perfect. The English translation isn't surprising given it's location. It makes sense it would be an Englishman doing the translating. I don't have any good suggestions for the odor.
