Have you tried an ammonia mix? It works great on cast aluminum before tig welding, but I have never used it on fiberglass. Maybe try it on a scrap and see if there are any ill effects, but I can't imagine it would be any worse than brake cleaner.

In dispair, I tried one of our household products - K2R. This is a spot lifter intended for fabrics. It is a spray that has a solvent together with diatomaceous earth. The solvent id one used by dry-cleaners and initself will break down oils. The diatomaceous earth acts like the talcum/cornstarch and lifts/retains any oily residue. Spray it on, wait 5 minutes, duat it off and repeat. Let the area rest a couple of days and repeat the cycle. It works.
Thanks to all for the input.
