BleachBit is a free software disk space cleaner, privacy manager, and computer system optimizer.


BleachBit was first publicly released on 24 December 2008 for GNU/Linux systems.[2] The 0.2.1 release created some controversy[3] by suggesting GNU/Linux needed a registry cleaner.

Version 0.4.0 introduced CleanerML,[4] a standards-based markup language for writing new cleaners. On May 29, 2009, BleachBit version 0.5.0 added support for Windows XP, Vista, and 7.[5] On September 16, 2009, version 0.6.4 introduced command line support.[6]

BleachBit is available for download through its website and the repositories of many GNU/Linux distributions.

As of October 15, 2009, BleachBit was more active than 99.972% of projects on [7] and according to the Ubuntu Popularity Contest[8] BleachBit was more popular than 93.44% of installed packages.



BleachBit is written in the Python programming language and uses PyGTK.

Most of BleachBit's cleaners are written in CleanerML,[9] an XML-based markup language for writing cleaners which is an open standard.[10] CleanerML does not only deal with deleting files, but also executes more specialized actions such as vacuuming an SQLite database (used, for example, to clean Yum).

BleachBit's file shredder uses only a single pass[11] because of the lack of evidence that multiple passes, such as the 35-pass Gutmann method, are more effective. However, multiple passes are significantly slower and may give the user a false sense of security by overshadowing other ways privacy may be compromised.
