Unmarking is the process of removing a mark or a designation from something. There are several synonyms that can be used in place of this word, including erasing, wiping, eliminating, obliterating, eradicating, canceling, nullifying, and abolishing. Each of these words has a slightly different connotation, but all describe the act of removing a mark or designation. Eradicating, for example, suggests a more complete or thorough removal, while nullifying implies that the mark no longer has any legal or binding power. Whatever word is chosen, the concept remains the same: something that was marked or designated is now being removed or canceled.
