NaOCl–CHX interaction and precipitate

My assistant gave chlorhexidine instead of hypochlorite, then gave hypochlorite, and para-chloroaniline formed. How should I remove it?

Translated version of the Turkish original

Unfortunately, complete removal is not possible. Inside the canal, it can be cleaned superficially by scraping with an H-file; in the cavity, it can be cleaned by using a bur.
