My 1983 '62 Vintage Re-Issue Jazz has been my main- and sometimes only- bass I've used since I bought it. It's very roadworn, most of the usual wear spots are down to the wood (alder, I believe). The problem I have is for years I moronically used lemon furniture polish on the body. Now I have a hazy, tacky finish in a few spots and that I can't remove. Tried Simple Green, lighter fluid, white vinegar to no avail; a tech at Sam Ash here in Jersey suggested an ultra-fine sandpaper. It actually affects my playing sometimes and picks up the scent of some of the dives I play. Any ideas?
