I believe that most compasses are filled with mineral OIL, not spirits.
Of course, I'd check the your specific manufacturer to be sure.

Mineral oil would be much too thick for a small compass, anyway and
might not work at all in cold weather.

Sincerely,

Does anyone know what type of liquid Plastimo uses to damp the card?



I'm not sure about Plastimo, but Silva uses mineral spirits.
