When the dogs have ear infections, the hair around the flap gets all greasy, too. I've never found anything that was very effective in removing the residue. Normally we just keep the area combed to prevent matting and let it wear off with time. If you do find something that works, for sure post back! I'll try it on the dogs, too!
