Both starting fluid and break clean make good degreasers as they don't leave a residue. I use them if I don't have anything better floating around. Don't smoke or do near any kind of ignition source if using starting fluid. That being said a degreaser used for paint specificly is always best.

I learned all I need to know about life by killing smart people and eating their brains.
