These are not the compounds I'd think at to remove gasoline. Most seem only to bring one more scent, possibly to hide the gasoline odour.
What about diluting first the gasoline spots with deodorized petroleum (or white spirit, or kerosene, or liquid paraffin - they're about the same thing, deodorized is the trick)? They will mix, diluting the molecules that bring the bad smell and easing the problem.
Then, rubbing alcohol is a diluent for gasoline, and the alcohol itself evaporates neatly. Not methylated spirits, they have an odour and are unhealthy. Try first on a hidden part of each cloth, as some textiles might perhaps be altered by alcohol.
Hexane would be an industrial option, but is less widely available.
