not wiping free space

Win 8.1

Free space wiper on hd (SSD) didn`t work, did a clean reinstall of ccleaner (pro, v. 5.48, registered). Same problem, won`t wipe (`Wipe` button greyed out). Any suggestions on how to fix this?

You can't and don't want to wipe a flash memory or ssd. It will drastically reduce your drive life.

ok, ta, Nergal, a friend`s coming for a visit and I didn`t want him to be tempted to read my messaging with my girlfriend...
