In a previous post GWE asked



Is there any difference at all between low odor mineral spirits, cheap paint thinner, and Stoddard solvent?

Well heres a site that gives breakdowns of what Stoddard is made out of.

Short answer is the govt considers it to be in the mineral spirits family.


Also the white spirits msds, a section of which I posted below.

General Synonyms: mineral spirits, high flash naphtha, petroleum distillate fractions, Stoddard solvent, petroleum distillates, white spirit Use: Paint thinner, degreaser Molecular formula: CAS No: 8052-41-3

There are differences in molecular weight distributions, and in impurities. The cheap stuff will have sulfurous impurities and very-low-volatility components that will goo things up.

By far the cheapest, reasonably pure petroleum distillate solvent is ... Coleman fuel, including the cheaper Wal-Mart store brand. Very light, very fast to evaporate. I use it by the gallon in a Sure-Shot sprayer.

What are you Sure-Shotting with solvent, just anything you wish to clean?

A little schpritz on parts to degrease them after machining, that sort of thing.
