What are some safe cleaners to use on my fretboard and everywhere else on the guitar?
wow, whats with everyone cleaning their guitars tonight lol. Baby wipes for life!!!

Or you could go crazy with the lemon pledge (like another guy on this section did)
Dirt adds character. Finger cheese on the fretboard forever!!!!

(for the body) A lot of cleaners like lemon Pledge and stuff like that are made for wood, not lacquer. They can actually ruin the finish by soaking into it and clouding it. Car wax is good. MacGuires Showcar Glaze #7 is teh sexy. Little dab'll do ya. Then just dust it with a dry towel every now and then.

I do leave the fretboard fingercheese though. Used to scrape it off with a pick. Couldn't be bothered anymore.
