I don't think this is a dup, this questions is specifically about deleting the free space. –  ripper234 Oct 11 '13 at 8:26

Try CCleaner. Go to Options > Settings > Wipe Free Space. It's free, but not open source.

Also, here is a list of utilities that should help accomplish what you want.

Hope that helps.

Good link in the post. I prefer Derrick's Burn and Nuke (DBAN), but as the website says, not for beginners –  Canadian Luke Nov 17 '11 at 23:13
    
@Luke, Good stuff -- I use that, too. Definitely not for beginners. And I believe it's called Darik's Boot And Nuke. –  Jeff Nov 17 '11 at 23:19
    
It's some form of Derrick, Derek, Darik or Derrek –  Canadian Luke Nov 17 '11 at 23:28

dban is for full system wiping, not free space wiping, and for that, dban is idiot proof –  Journeyman Geek Nov 17 '11 at 23:46
    
Yep, dban is for completely (and securely) wiping a drive, not for wiping free space. My bad. –  Jeff Nov 18 '11 at 10:40
