Let me ask the dumb question,
where do you buy kerosene? I would think Ace or Home Depot, as they
sell the kerosene heaters. Is that right? And is kerosene a good
cleaner?

At paint stores and the paint aisle at big-boxes at an insane retail
markup. Or WD-40 if you like it perfumed.

Diesel fuel is close enough for degreasing applications.

Filling stations sell it from pumps in rural, cold climates for heaters.
