I poured some acetone in a glass, put the pony in, and walked away. After, mm, maybe 10 minutes, I swirled the pony around and all the glitter came off. It was zero work, haha. You might need to use a qtip or cotton ball to wipe away stray glitter but it's very easy. The plastic can get a bit soft but it will set up again. Just be careful not to squeeze or use anything that might dent or scratch the plastic while it's soft.
