Kerosene & polishing compounds

I don't know what you're polishing, and what polish you use, but
if kerosene works, chances are that WD-40 will work, or lamp oil,
both available in small quantities. 

WD 40 is mostly Stoddard Solvent (similar to kerosene but a little
more volatile) and light mineral oil and 10% inert ingredients. Lamp
oil is “odorless” kerosene basically a highly refined kerosene. I
would stick with the lamp oil.
