Lets face it, every once in a while we make a mistake with CA glue. BSI's Un-Cure will soften up CA glue in case of a mistake and let you separate the parts without destroying them.
From BSI about Un-Cure:
UN-CURE™ debonder will soften cured CA. If parts are bonded incorrectly or your fingers are stuck together, a few drops of UN-CURE™ will dissolve the CA in about a minute. Apply on bonded skin and roll apart fingers. Once stuck, use acetone to clean off softened CA, then wash off with soap and water. Since cured CA is essentially acrylic plastic, anything that will dissolve CA will also soften most plastics. Care must be used, therefore, when using Un-Cure on plastics. Separating plastics parts with a razor saw is usually the best option.
