Get a plastic tub / with lid big enough to hold it. Get a gallon of Castrol Super Clean (the purple stuff) or a gallon of Simple Green, both are under $10, at the local Wally World or equivalent, or enough brake fluid at a local auto parts store. Cover and soak for a day or so, then lightly scrub with an old toothbrush. May take a couple of soaks to get it all. Wash in a mild dish soap to clean all residue and air dry.
Only do in a well ventilated area and don't leave the tub and fluids indoors. Don't mix any of the above with each other. Use as it comes from the jug.
The others hit it right on. Breaking the film on enamel will cause it to lift and wrinkle when it is not fully cured, take it from an old auto painter. Been there, done that, and have a few shirts in the drawer to prove it. And they were lots bigger goofs.
Good luck on getting it off and ready to reshoot. Yep, learning experience for sure. Sorry it happened to you, but we all have paint mishaps and get better at it in time.
