Re: Polar or non-polar, that is the question...
Acetone and Methyl alcohol are polars,
toluene is np.
This 3 things sound like a brake parts cleaner of some sort, extremely dry,(canned brake parts cleaner) acetone is the dryest acetone you can get. its fuckin miscible in toluene when canned. you cannot dry acetone with epsom shits like it is when it comes in a spray can.

Re: Polar or non-polar, that is the question...
good luck finding pure tone in a spray can though... they usually always use it as part of a mixed cleaner.
All of the alcohols are polar. Toluene, xylene, naptha, TCE, turps, are all Non-polar.
Try testing any solvent by pouring it onto water, the top layer is usually the Non-polar or also called organic layer(TCE is an exception as it will sink below water)
