The 5 Best CCleaner Alternatives in 2026
If you are tired of pop-up ads, bundled software, and background telemetry daemons, here are the top 5 cleaners tested for Windows 10 & 11.
Quick Summary: Top Picks at a Glance
- 1. SWEEPR Cleaner: Best overall for modern Windows 11 users. Built in native Rust (<15MB), zero background processes, 60s scan speed, duplicate finder, and military-grade file shredding.
- 2. BleachBit: Best open-source and free option. Transparent and powerful, but has a dated UI and lacks RAM optimization or automatic duplicate merging.
- 3. Windows Storage Sense: Best built-in tool. Completely free and built into Windows Settings, but misses third-party browser caches and stubborn uninstalled app files.
- 4. Glary Utilities: Comprehensive legacy suite, but carries a heavy background footprint and occasional upsells.
- 5. Wise Disk Cleaner: Fast manual cleaner with decent custom rules, though dated interface.

Platform: Windows, Linux | Footprint: ~12MB
BleachBit is an open-source veteran. It is completely free, contains no advertising, and allows granular deletion of system and application caches.
The trade-off: The interface looks straight out of Windows 98, and inexperienced users can easily check boxes that delete saved browser sessions or system state without visual previews. It also lacks startup and RAM optimization tools.
3. Windows Storage Sense (Best Built-in Tool)
Platform: Windows 10 & 11 Native | Footprint: 0MB
Built directly into Windows Settings (System > Storage), Storage Sense automatically empties the Recycle Bin and deletes old temporary update files.
The trade-off: It misses third-party application caches (Discord, Spotify, Steam, Chrome Service Workers), does not uninstall leftover app files, and has no file shredding or duplicate photo detection.
