I just used my new food processor for the first time and without thinking, put chunks of butter into it. My question is: Is there a way to make it Parve again? I’ve only used it that one time. Other things that were processed along with the butter include garlic and nuts. The processor bowl is made of plastic and the rotating knife is metal. None of the ingredients were warm/hot.

One may imerse the bowl and knife in boiling water, and use for pareve.
