Kim, if you're like me, you will try to hang on to a nib for far too long! When it starts acting up - scratching, dragging, blobbing, spitting ink, etc. - cut your losses & say, "Goodbye!" As Schin said, nibs are relatively cheap and there is no reason in the world to ruin a piece just because a $1.50 nib has decided to die! Do you have a little pair of pliers? I got a little pair in the jewelry-making section at Michael's or Hobby Lobby. They really help to remove nibs, which can sometimes more or less "rust" into place and put up a fight about coming out! I also use them to insert nibs into the holder, so as to avoid getting oil from my fingers onto the newly cleaned nib!
