for the neck and finger board, i use spit. someone reccomended it, and it really worked to really make it silky smooth and soft and fast. Spit into a cloth, rub it down, almsot polish it with spit. than repeat with a cloth that is damp (with water) to remove spit (thats gross) and smell, chew gum before, makes ur guitar
smell minty fresh. for the body, just a water dampened cloth....
