CleanerML Repository

This repository is an experiment whether GitHub provides an efficient platform for a community to develop safe and effective system cleaners. If the experiment is successful, BleachBit will provide automated access to this repository to support a wide variety of applications. For more background read the announcement.


CleanerML is a simple yet powerful markup language for writing cleaners. Most of BleachBit's cleaners are written in CleanerML, and you can write your own cleaners in CleanerML too.

You can think of it as writing XML to delete files, but it is more powerful than that.


BleachBit is an open source system cleaner for Windows and Linux.

How to contribute

  1. Download BleachBit
  2. Read Documentation on CleanerML
  3. Read Contributing a cleaner
  4. Help testing untested cleaners in pending/ and submit an issue to have it moved to release/, or deleted.
  5. Write your own cleaner or review someone else's submission

How to use

In the future automated sync may be as easy as checking one option, but for now you must manually download and copy the files to your personal cleaners directory. The easiest way to find the directory is to open BleachBit, click Help, click System Information, and look for personal_cleaner_dir.


The directory pending contains cleaners that are waiting for someone to verify they are safe and effective. The directory release contains cleaners that are considered safe and effective.

Additional information

Your cleaners should retain the copyright and information header found in release/*.xml. Please edit the copyright information accordingly. If needed, you can also include extra maintenance information in the header, as found in release/openshot.xml:

@note Some notes for cleaner maintainers
