FluentCleaner: Free Open-Source Windows Cleaner Without the Bloat - Firethering
FluentCleaner is a free and open-source Windows cleaner built as a modern alternative to traditional PC cleaning tools. It focuses on removing unnecessary files without scareware, spyware, dark patterns, aggressive upsells, or questionable registry magic. Inspired by the simplicity of the classic CCleaner, FluentCleaner uses the widely known Winapp2.ini cleaning ecosystem while adding its own curated cleaning database, safer exclusions, and a modern Windows interface. It is available in two editions: a modern WinUI 3 version for newer Windows systems and a lightweight Classic edition for users who prefer a much smaller application.
