Contrary to this instruction in an old Pfaff service manual, we will not be dousing any machine in any amount of kerosene.

@W6KME Yes, the old gunk needs to be removed.
No, we don't use kerosene for that. In our shop, we use 90+ per cent isopropyl alcohol instead. In evaporates and leaves no trace afterward.
@evergreensewing Yep, I like alcohol too. I'm talking about those machines that a good cleaning isn't going to help. Time for the 5 gallon bucket of kerosene, at least for machines with plastic parts that penetrating oil and torches aren't an option for. The last was a 1911 White Family Rotary that had been yard decor for years.
Mind, I like fixing machines that are beyond repair. I'm an antique machine restoration buff who can service sewing machines, not a sewing machine tech.
