Any util' that will "wipe" only free space?

Tech-Archive recommends: Fix windows errors by optimizing your registry

Try to find a utility that will wipe the free space on my boot volume.


I compress my boot volume, use it for a backup in case of disaster.

Volume compresses a lot better when free space is "wiped" to be all hex
zeroes.

Problem is, all the wipe utilities seem to wipe free space with random
ascii characters _instead_ of using hex zero.

FWIW, by boot volume is 48 GB.
