The method of cleaning the fret board and underside of strings is as follows: Feed damp cloth under strings - down by the sound hole, so you have a piece of cloth in each hand with the main part laying under the strings. Gently slide the cloth up toward the top of the neck and then begin a sawing motion from left to right whilst applying downward pressure to the cloth. Work your way all the way to the end of the fret board in this manner and then repeat the operation, this time applying VERY GENTLE upward force to the ends of the cloth in order to de gunk the underside of the strings. To finish use the same method with a dry hanky to polish everything. Recheck tuning, put axe in nice case and kiss it goodnight...well I do!
