Remove super glue stain from hard plastic?

Depending on the glue manufacturer, these can be used to remove superglue- acetone(nail polish temover), cooking oil sprays such as Pam, and lighter fluid. Do not mix these are to be used seperately. I would first try the acetone as it usually works best. Try dabbing a q-tip into the acetone and checking a part of the figure like maybe the back of the neck to make sure it doesn't discolor the plastic. Let that dry for a couple minutes then wipe it off with a damp cloth. Then check the spot. If it's good use the same method on the glue. If it is deeply bonded you may want to use a soft tooth brush with the acetone to lightly scrub the area. You could try using a pedicure polishing cube to remove the glue as well. If the doll is painted you may want to try the steps for the acetone with the cooking oil instead. Some glues flake off in layers, so you may need to do this more than once.
If you don't want to risk damage- get a doll of similar plastic. Put the glue on the doll, then attempt to remove that. Likewise; you could try a part of the doll such as its back if you can't get ahold of a similar one and the back is made of the same type of plastic! Hope this helps some!
