Re: Wiping Down Guitar
As soon as I get home from a gig, I wipe them down, including strings, with a damp rag and then dry with a terry cloth towel. Water will remove 99.8% of contaminants. When the strings are dry, I go over them with the Dunlop 65 String Cleaner. It leaves a light, protective coating on the strings and gives them longer life.
My NCL-finished guitars get a coat of Carnauba wax 2-4 times a year. Fingerboards get oiled as needed. I like the Dunlop 65 Cleaner and the Conditioner. I do not use lemon oil any more. I also will use Gerlitz Guitar Honey on a dry board. Poly-finished guitars will hold up better, with minimal care, but I do keep them clean and polished.
I really try to take great care of my guitars. It makes sense to me to take care of my tools...and my investments. I really don't like a dirty guitar. I've bought a couple of used ones that took hours to clean up; the seller probably would have got more money out of me had they been better cared for.
Of course, if you're going for the relic look, ignore my advice.
