I've put the job off too long. I thought lighter fluid was the cure-all for this kind of thing, but it doesn't remove the gunk on the lacquer finish.
For a moment, I thought the naphtha was removing the lacquer, but gently scratching the deposit for a fingernail removes it. A lot of this is in tiny spaces around rods and springs, but the larger areas can be rubbed. With what, though? Some very light abrasive liquid, like the one used to clean vitro stoves? Is there a product made for cleaning the finish without removing it? Hobs don't have a finish so I didn't rush to try that stuff.
