Homebrew PCBs

Steve,

I didn't catch the lighter fluid when I first read your post.  JRW is right - it leaves a coat of oil.  In addition to his suggestion you may try lacquer thinner.  I prefer just plain water - no detergent - and scrub with a scotchbrite pad until you get a water break free surface.  Hold a wet board vertically.  If there is any oil water will bead up like on wax.  If it is really clean the water will just sheet off without any sign of beading.   If you use a detergent, detergent residues may mask the presence of small amounts of oil.

  The lighter fluid has too many 'heavy ends' and will leave an oily film.  Try alcohol or
  acetone, in a well ventilated area,or any solvent that does not leave a residue and removes
  any oil film present.
