Acetone will dissolve CA glue, but it takes time. As others have
mentioned, make sure your part does not get damaged by the acetone
soak.

I need to remove all the glue so I can
start over.

There are products made specifically for de-bonding CA:

In my experience, they leave a residue that makes it impossible to get
the glue to stick to the same spot again. I use CA mostly on wood.
Getting the residue cleaned off a hard surface might be possible.

Cured CA is hard to remove. There are several "de-bonders" sold for
CA. Not all are the same. Some are basically acetone, some methylene
chloride as has been said already. I have tried both and cannot say
that I am impressed by either.

The fencing armourers tend to use CA to wire epees and foils. Much
argument has been made as to how to remove the old wires. I personally
use heat gun but those who deal with volume swear by acetone baths:
They put several blades into a bath for as much as 24 hours. Whether
your item would tolerate such treatment is a big question.

As far as suitability of CA as an adhesive, I would say horses for
courses. I possess no fewer than four industrial CAs. Each has its
well defined purpose. Even in the narrow confines of re-wiring epee
blades some blades take one type of CA better than another. I also
possess no less than ten other types of glue, each with its specific
indication. I have been known to use four different glues on a single
piece.

YMMV
