If your PCR fragment is longer than 200 bp, you can also use Geneclean.
Anything below that size does not bind to the glass particles;
you can wash the glass several times to get rid of all the remaining
primers (I have tested it with 32P labelled primers) and elute
your clean PCR fragment.

Good luck !
