A parev knife was accidentally used to cut meat. It was then left for a few hours without being washed. It was then washed with a meaty sponge. Is it necessary to kasher the knife? Thank you very much
If the meat was hot then the knife needs to be kashered, however if it wasn’t hot then the knife is not considered meaty from the meat.The fact that it was washed off with a meaty sponge in retrospect will not make it treif if the sponge had soap on it, because the soap will nullify the meaty taste.
