One of my pals originally from Brazil told me he use to boil his bass strings to make them last longer. Another told me the he heard the same thing from his bass teacher. Whenever he gigs, he sweats a lot. After 6-7 hours of gigging he boils his strings to remove the sweat and dirt. They don't go back to brand new, but they really do get much better. I just changed to flat wounds on my PRS and the round wounds weren't that bad, so I boiled them and put them on my Musicman. They sound almost like brand new. Just though I would pass along the tip and see if anyone else had had a similar experience.
