can't get naphtha in my country was wondering if 'fuelite' would be a good substitute?

Description as follows:

"Fuelite is a water white, medium cut, aliphatic petroleum solvent and fuel containing approximately 90% saturated hydrocarbons in the range C5-C10, and 10% napthenes and substituted monoaromatics in the range C6-C10. It is a relatively fast evaporating, non-corrosive and chemically stable hydrocarbon solvent with a mild odour and very low aromatic content."

UN - 3295

Other common names Aliphatic Hydrocarbon Solvent, Petroleum Spirit, Peg 1425, Calite, shellite, Pegasol 1425, Fuelite brake cleaner.

Sounds perfect. The (up to) 10% of aromatics may affect freeze precipitation although since they state it has "very low aromatic content" that shouldn't be an issue. This means the 10% is largely 'naphthenes' - an outdated name for cycloalkanes. Given the exceedingly low polarity of cyclohexane (which is likely to be than main cycloalkane present) you'll probably have to warm the solvent, or the base soup, slightly to get best results when doing pulls.

Please ensure you are aware of how to handle flammable solvents safely! (No naked flames or incandescent material, beware of sparks from any kind of electrical switch, thermostat or motor.) <- [Thought it would be best to mention this since I suggested warming the solvent. Safety first!]
