Which tool should I use to wipe free space on Windows 7?

It should be free and preferably open source.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

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
