Looking for some maintenance advice. I bought a DV-52 about a year ago off Ebay. The guitar has a hand rubbed finished. It wasn't in the best shape when I got it, and I really didn't baby it ever since I got it. I like playing it so I usually just leave it out in the living room so I can grab it when ever I want. Now I am going to put some new strings on it and want to do a thorough cleaning. I couldn't find much information on how to care for guitar with hand rubbed finish. Can someone give me some tips/advice on what products and what procedure to clean and condition it? Thanks.
