What many people fail to realize is that any oil based finish cures by polymerization (an oxidizing or slow "burn" if you wish)
unlike an evaporative cure.
That is why balled-up oil soaked rags catch fire.
Leave them spread out, no problem, the heat dissipates.

A lacquer thinner soaked rag will never catch fire, as the evaporation is a cooling process.
