Yep. The older Singer manuals all say that if your machine gets balky, or some yahoo has lubed it up with 90-weight or suet, just douse the whole mess with kero (which DOES smell, even the "descented" iterations sold as lamp oil), then run it for a minute or two and reoil. I've never actually done that, but have taken comfort in the idea that kero will not harm Singer finishes and decals. I use cloth and kero on larger surfaces, then use qtips and kero in problem areas like those hardened smirps around around oil holes. For those little rust pips on nickle, I use kero, wd40 in a pinch and the finest BRONZE wool, which seems softer than nickle so that you can scrub it pretty well. I don't go for restored-like-new, more for used-but-well-cared-for, so I don't wax anything. I just rub 'em up gently with a very little kero/light oil mix I use with my oil stones on a piece of old sheet. We all have our magic potions.
