Boiling strings is akin to wiping your ass with a washcloth and throwing it in the clothes hamper to be washed. Strings are relatively cheap and unless you gig 5 hours nightly you don't need to change strings every couple days. It's a myth IMO; brand new strings sound too bright and have tuning instability for awhile. Strings with a bit of use aren't bad until they start sounding dead...noticeably dead.
Bass strings are another story. I love old strings on a bass as they're more woolly and thuddy; seem to add to the bass sound I'm after. I have black nylon flatwounds on my bass and they're at least 10 years old. They sound great. Granted, regular roundwounds might need changing more often and if you slap or prefer a bright tone.
Yeah buddy! I've got old string on pretty much all my instruments. My electric guitar strings only got changed this summer because my old guitar got stolen, and the new one didn't come with a full set.
cheap + lazy + grunge/punk tendencies = old strings.
I did boil some of my bass strings once, but my water had visible minerals and debris in it, so I haven't bothered to use those strings.
