Hmm... I like to take a slightly different approach with the de-greasing aspect.
Get rid of the "grease" early in the preparation process either by using solvents or warm water / soap etc. When you get to the final sanding
stages, keep your finger tips OFF the surface. Don't feel for smoothness by using your finger tips, look for it using your eyes.
Remove the dust etc with a good vacumn cleaner (with a clean brush) and then paint. For a really top finish, vacumn at least twice with a few hours minimum between cleaning
to collect the dust that settles from the air after the first cleaning
Doing a solvent wipe down just before painting usually introduces more contaminates than it removes IME - mainly because one doesn't use enough solvent or replace the paper or cloth wipes after every wipe or so and therefore ends spreading whatever contamination there is, all over the job.
