Hi Guys
Why would you want to use a solvent which is less effective than another one.
It is worth carrying acetone, isopropanol, white spirit, Chemspec pog, toluene, meths and then you can work out which works better and then you have added knowledge.
I remember an old lecturer of mine being a big advocate of solubility parameters, something that doesn't seem to come up much now.
Essentially it is a way of predicting which solvent will work best on which substance.
Blends can only ever be a compromise, single malt sir!
Cheers
Doug
