I would try giving the cabinet a cleaning with a cream hand cleaner like GoJo just to see what you have, after that then you can make a judgement about what to do next. However it looks to me like the lacquer is starting to detach itself from the wood in places like on the side, those white and yellowish spots and cracking are evidence of that. One the lacquer get like that it means that it's pretty much done, no amount of magic liquid in a bottle will fix it, in fact using some products, like wax, will soak into the wood and may make it more difficult to refinish in future.
