Why should I use RJL System Cleaner instead of a free open-source...

Open-source cleaners like BleachBit are excellent tools and we respect them. Here is what RJL System Cleaner offers that most open-source cleaners do not:

  • Safety ratings -- Color-coded Safe/Caution/Review ratings on every item, with a Review gate for risky items. Open-source cleaners typically show flat checkboxes with no risk differentiation.
  • Duplicate file scanner -- Built-in detection of identical files wasting space. No open-source cleaner includes this.
  • System Restore points -- Automatic restore point creation before every clean. No open-source cleaner does this.
  • Modern Windows 11 UI -- Native VCL styling with light and dark mode. Most open-source cleaners use cross-platform toolkits that look dated on Windows.
  • Two view modes -- Simple summary for everyday users and advanced detail for IT professionals. Open-source cleaners typically only have the advanced view.
  • Speed -- Native compiled code (Delphi) scans faster than Python or Java-based cleaners.
  • Under 5 MB -- Smaller than most open-source alternatives.
  • Mom-friendly -- Designed so a non-technical user can scan and clean without understanding file paths or technical terminology.

If open-source auditability is your priority, use BleachBit -- it is a fine tool. If you want the safest, easiest, most transparent cleaning experience on Windows, RJL System Cleaner is built for that.
