I am brand new to acoustic DB. I have owned a custom EUB with actual 3/4 DB neck, Bridge,ebony fingerboard, tailpiece, saddle, and endpin plug. So I am familiar with the parts, just not the instrument. I just purchased a 1942 Kay M1 DB. Before purchase I had the seller take extensive pictures of the bass. No cracks, or any other visible structural damage on the bass. Not even major scratches, or huge worn spots in the finish. It looks amazing for a 78 year old DB. The DB is missing the bridge, so I will have my luthier locally carve and install a new bridge for it. All fittings are ebony except of course for the endpin plug which is metal. My question is... Before I turn the bass over to my luthier, what can I use to first clean the body, and neck, fingerboard without damaging the finish on the body. Also is there anything that is recommended to possibly revitalize the finish and ebony fittings? For the finish I was told guitar polish would work fine for the body as long as there is no silicone in the polish. What are your thoughts with this? Thanks in advanced.
