RENEW THE SOUND OF METAL STRINGS BY BOILNG THEM: There are a few reasons that the sound of metal musical instrument strings become dead and thuddy as they get older --- but by far the main offender is the accumulation of finger oil, dirt and other crud in the string's windings that builds up over time. Boiling removes most of this crud and dramatically brightens the tone, often to near-new sound. Simply coil stings in a coffee can or other pot that you don't mind getting dirty (you'd be surprised how much grime boils out sometimes) and boil hard for five or ten minutes. I've never had this boiling process harm strings in any way. While still hot and wet, wipe them down thoroughly with a cloth (protect your hands with leather gloves). Make sure the strings are amply dry before re-stringing. This boiling method, which only works for wound strings (it has no effect on plain, un-wound strings which don't have winding-grooves for crud to hide), is nothing new, but in every case I've ever tried it over the years, it greatly improves the tone. I've read some postings on the internet that claim boiling strings dosen't work -- Huh!!? -- I don't understand why anyone would claim this, the "before & after" difference being SO remarkable. Another claim is that any improvement caused by boiling is short-lived --- I have never found this to be the case. Makes me think these people never really tried boiling strings. In any event, the "proof is in the pudding" -- try it! - there's little to lose and a whole lot to be gained. Brightens the sound right up. Dennis HavlenaClick here to access my home page.
