I just cleaned my guitar like 2 or 3 weeks ago. People like myself who have CF, our skin and sweat salt content is really high. All that you are seeing built up is salt. This was accomplished by playing 4-5 hours a day since changing my strings. Which by the way, my strings go to shit after just two or so days. The build up on them are much worse, but a picture of those would be hard.
