Query: Totally removed bicycle grease

I dumbly stored my bicycle on top of a bright yellow bicycle shirt, picking up the grease from the bike chain, and was certain it was ruined. I left Gonzo on the shirt for several minutes, then by rubbing the stains with a paper towel it completely, totally removed the stain. Not one trace of the grease is left.
