I am kashering some keilim that I have used previously, and they were toiveled before their original use. Some of the items are silverware that was used with the wrong type of food. The other is a grill pan that I found out should really be kashered before use. After the kashering process, is toiveling necessary again?
Regarding the silverware there is no need to tovel them after they are kashered. We only have to tovel vessels that were acquired from a non Jew. Regarding the grill pan, why does it have to be kashered? If it is Is it because it was bought from a non Jew, or even new according to some poskim, then it would need tevilah, but not because it needs kashering, but because it was bought from a non Jew.
