BleachBit

BleachBit is a powerful, open-source system cleaner designed to remove junk files, free up disk space, and protect your privacy on Windows systems. Unlike many commercial cleaning utilities, BleachBit is fully transparent, lightweight, and free of ads or telemetry. It targets unnecessary temporary files, caches, logs, cookies, session traces, and many other sources of digital bloat that accumulate during daily computer use.

BleachBit works at a deeper level compared to traditional cleaners. It can securely wipe free disk space, shred selected files, clean system-wide logs, and even remove software leftovers that most tools cannot detect. With its automation support and extremely lightweight architecture, BleachBit is widely trusted by privacy-focused users, IT technicians, and digital forensics professionals.

It is especially useful when:

• You want to clear browser caches, cookies, and history
• You need to remove system logs, update leftovers, and crash dumps
• You want to securely wipe files or overwrite free disk space
• You prefer an open-source alternative to tools like CCleaner
• You want to automate cleanup tasks using command-line scripts
• You need a portable cleaner that works without installation

Key Features

• Deep application cleaning: supports over 100 apps including Chrome, Firefox, Edge, VLC, LibreOffice, Discord, Steam, and more
• Secure shredding: permanently deletes selected files with overwrite protection
• Free space wipe: cleans residual data from previously deleted files
• System-wide cleanup: removes Windows logs, temp files, crash reports, and update leftovers
• Portable version available: no installation required
• Automation support: fully scriptable via command line
• Open-source GPL license: no ads, no telemetry, no tracking

Compared to traditional cleaners, BleachBit prioritizes security and privacy. Commercial tools such as CCleaner have historically included advertising components, telemetry, bundled software, and even security incidents. BleachBit avoids all of this with a clean, transparent open-source architecture.

For a broader system cleanup, you may also explore tools like TRON Script, Optimizer, or Blackbird — each complements BleachBit in different maintenance scenarios.

When BleachBit Is the Best Choice

• You want maximum privacy with zero telemetry
• You prefer open-source tools instead of commercial cleaners
• You need scriptable automation for regular cleanup routines
• You want a portable cleaner that runs without installation
• You need a lightweight tool for older PCs or minimal Windows installs
• You want a cleaner safe for professional environments and forensics labs

BleachBit is especially popular among technicians preparing systems for resale, cleaning malware leftovers, or wiping sensitive data before imaging tools such as Clonezilla or Rescuezilla are used.

Download Options

How to Use BleachBit

1. Download the installer or portable ZIP archive
2. Launch the program and select the items you want to clean
3. Review cleanup categories (browsers, logs, temporary files, etc.)
4. Click “Clean” to remove selected items
5. For secure deletion, use “Shred Files” or “Wipe Free Space”

System administrators can use the command line mode to automate daily, weekly, or monthly cleanups as part of maintenance scripts.

Troubleshooting & Tips

Some applications do not show up in the cleaner list
Not all software is supported by default. BleachBit updates its cleaner modules regularly, so ensure you are using the latest version.

Low disk space after cleaning
Windows creates large update backups and system restore points. Use Optimizer or Windows’ built-in Disk Cleanup to remove Windows Update leftovers.

Slow wiping operations
Secure overwrite is slower by design. For standard cleanups, disable free-space wiping and focus on regular file cleanup.

Portable version does not save preferences
This is expected. Portable mode stores settings in the same directory as the EXE and may require write permissions.
