BleachBit is best junk cleaner in Ubuntu

I think BleachBit is best junk cleaner in Ubuntu computer system. Everyday we visit internet, do many work, done huge file works and made a ton of junk file in temporary folder. This process can fillup your harddisk space. So we need to clean them manualy. There are some system cleaner software available for Ubuntu linux (All version). But in my opinion BleachBit is the best junk cleaner in Ubuntu world.

Why?
In description page it says:

BleachBit deletes unnecessary files to free valuable disk space, maintain privacy, and remove junk. It removes cache, Internet history, temporary files, cookies, and broken shortcuts.

It handles cleaning of Adobe Reader, BAsh, Beagle, Epiphany, Firefox, Flash, GIMP, Google Earth, Java, KDE, OpenOffice.org, Opera, RealPlayer, Rpmbuild, Second Life viewer, VIM, XChat, and more.

Beyond simply erasing junk files, BleachBit wipes free disk space (to hide previously deleted files for privacy and to improve compression of images), and securely shreds arbitrary files.

How to get?
This useful software is available in Ubuntu Software Center. Type 'BleachBit' in searchbox and hit Enter.'
Now install it.
