I have a 76 gibson grabber that i love to death. But it seems like every time i go out and play a show it feels like the neck finish is coming off. I know thats "probably" not the case but it feels like little dirt balls form in my fretting hand every time i play the thing. It's not my hands being dirty. I dont know if the finish is coming off or old cleaners/polish like wax(that i didn't put their) are rubbing off. Is their a way of makeing it stop doing that (without sanding)? Or a cleaner that won't build up so the problem does'nt come back?
