The strings also last longer if cleaned.
Happy cleaning and guitar playing

Besides, for those relic guitar lovers, they should hire you to play their guitars.
If i were you I wouldn't have any problem about my sweaty fingers as it would be cool to easily make a relic on my finger board naturally, but that's just a personal taste ;)
