Null unused/available hard drive space

Can someone tell me how to place null values in unused/available hard drive space.

These areas contain files and data which had previously been deleted.  However,
I want to null these remaining files and data so that they can not be recovered
or 'undeleted'.  

Is there a way to do this ?  Or an application on the market that will do that for me ?

Thanks !   Dan R.

The most popular is CCleaner. You have an option called "Wipe free space".
You can set it up to do a "normal" delete or a "secure" delete with a configurable number of overwrites.

If you want to delete a whole HDD, DBAN is another popular option.
