Boil your string for tone??

Sometime ago I heard you can get good tones if you boil your guitar string.Later one of my friend Naim boiled his bass string cause he don't wanna buy a new string."Mahal bang" he said..its expensive in english.He thought it would clean up the string and maybe bring back the ring..he told me it worked..Well good for him.

Well I don't know about that,so recently I thought I do my own mythbusting with a set of old bass string,and to tell you the truth..I don't any hear any difference..Maybe its my ears..Haha
