Boiling Bass Strings for better sound?

Basically, you bring water to a boil, then place the strings in and let them boil for about 15 minutes. Take them out, lay them across a towel, pat them dry, and let them sit for a bit to cool down to room temperature. You don't want to restring them immediately because, being thin strips of metal, the heat will make them a bit maleable and if you string them too soon, you'll have to tune them a number of times before they “set.”

But I'd only recommend doing this if your strings are noticeably dirty, or if they're old and you can't afford a new set right away. I've heard of some players doing it after every couple gigs but I can't imagine a set of strings lasting too long if you're regularly subjecting them to such alternating temperatures.
