There's lots of threads on this already, try doing a search next time.

But yeah.. boiling it should do the trick, but don't change the temp of the water too quickly or it'll crack. Don't drop the pipe straight into boiling water, let it heat up with the water.. let it cool on its own. But I've heard boiling MAY not be good for pipes. Just use some rubbing alcohol and salt (i've done this before).. works pretty well, just make sure you rinse it really well afterwards.
