BleachBit is a free and open-source disk space cleaner, privacy manager, and computer system optimizer. The BleachBit source code is licensed under the GNU General Public License version 3.
BleachBit was first publicly released on 24 December 2008 for Linux systems. The 0.2.1 release created some controversy by suggesting Linux needed a registry cleaner.
Version 0.4.0 introduced CleanerML, a standards-based markup language for writing new cleaners. On May 29, 2009, BleachBit version 0.5.0 added support for Windows XP, Windows Vista, and Windows 7. On September 16, 2009, version 0.6.4 introduced command-line interface support.
BleachBit is written in the Python programming language and uses PyGTK.
Most of BleachBit's cleaners are written in CleanerML, an open standard XML-based markup language for writing cleaners. CleanerML deals not only with deleting files, but also executes more specialized actions, such as vacuuming an SQLite database (used, for example, to clean Yum).
