Can a parve utensil be cleaned with a fleishig sponge and still remain parve?
The utensil would remain parve provided that one of the following three conditions were met:
1. Cold water was used to wash the utensil.
2. The sponge had not been used for fleishigs for twenty-four hours or more, and there were not actual pieces of meat on it.
3. Soap had been added to the sponge, and there were no actual pieces of meat on it.
If any one of the three conditions are met, the utensil remains parve.
