I just purchased a Badger Air-Brush Co. 260-1, but from the looks of the previous posts the abrasive media that comes with it is junk. I'm going to try to use it on the top "rough part" of Meg Teeth that I get out of Venice. I've tried the vinegar and dental picks, but I don't like the color bleaching that can happen, nor can I get into every single crack with a dental pick on encrusted teeth. What do you guys recommend for me to try with this brush? Here's an example of what we normally pull out of the ocean before any cleaning.
