Yes, acetone will take most anything off! paint, decals, ...your skin

I would try masking the decals and sanding CAREFULLY around them with 1500 or 2000 grit sandpaper.
Then mask that masking tape and use 1000 grit to carefully remove the rest of the offending paint.
But be prepared to have the frame repainted!

Trying to remove just the top layer of paint aint gonna be EASY!
