I work as a industrial chemist for a US company here in Oz

White spirits - refined from oil , comes in three different grades with different boiling points (130 - 170 degrees centigrade), plus an extra grade in the US called stoddard solvent. The lower the boiling point the faster it will exaporate. The grades are industrially known as low flash, regular and high flash)
Mineral turpentine is a type of white spirit but contains more aromatic character and has a higher boiling point. The effect of this will be to dissolve other organic components better but take longer to evaporate. One lot of white spirits from one maufacturer may not be the same as from another as each refinery will produce things slightly differently

Methylated spirits - 'metho', this is ~95% ethanol with ~5% methanol in (so you cant drink it!. Boiling point around 70 degrees centigrade, evaporated far quicker and in general is a worse solvent for organic materials(but more water compatible)

Thanks Brit-in-Oz.

What's parrafin ... the same as kero here?

And if a can of spirit stain says 60% hydrocarbon, any idea what it's likely to be? White spirit?

Just to correct some dud info on "Methylated" spirits.

Originally ethanol was "methylated" with methanol as described. But the trouble was that methanol tastes like ethanol, so people like my grandpappy did not recognise that they were drinking metho until they carked it.

So the powers that be decided to "methylate" ethanol with pyridine, which tastes lousy, and is hard to remove. Cut down grandpappy's drinking greatly. He had to flavour it with bootpolish and other stuff to mask the pyridine.

To this day, the "methylated spirit" you buy off the shelf is the pyridine version.

Perfumiers and others using ethanol as a solvent can still get true "methylated spirit", provided they are going to add stuff which will act like pyridine to make the brew unpalatable.

Hi All

I remember this topic from an earlier thread. The following link is a handy reference:
