Anything that could remove it could also damage the plastic.
Any super glue will bind hard plastic.
There is almost no way to do this without destroying the plastic. As you didn't say WHAT KIND of plastic, it's hard to be more help.
First identify the 'plastic' then find it's solvent.
Hard super glue is no longer usable.
Any smooth, hard surface can be glued by Super Glue.
Yes, super glue works on anything smooth and hard.
You chip off A piece of hard suffice with the glueANS 2- Use a single side razor blade or a sharp craft knife and gently slide it under the edge of the hardened glue
You may take Goo Gone and rub it in, in circles, until the superglue comes off. Or use Goo Gone multiple times until glue is off of the surface.Actually goo gone is NOT SAFE for use on plastics and will "melt" the plastic surface. This damage is NOT repairable (I found out the hard way!) ORUse rubbing alcohol - take a q-tip, dip it in the rubbing alcohol, and rub at the dried glue until it softens. Then wipe or rinse it away.ANS 2 - You can NOT successfully remove superglue from any plastic. It almost always mars the surface.
I have known super glue to dry out and fail if glued to a very hard, smooth surface.
Rub it hard with a rough rag and Goof Off. After a minute or two it will degrade and you can scrape it with a wood spatula.
Because they super glue it to their heads
Super sticky and it will become hard like a stone texture.
