    BleachBit is open source and does a thorough job of deleting various files that could reveal what you've been up to, from cookies to temporary files and other junk. It can't replace CCleaner on Mac, but on Windows and Linux it is arguably better and more trustworthy.

    It doesn't have an automated option as far as I can tell, it seems to only work manually.

    It's FOSS, no bloat, and does a perfect job.

    Noah fixes what's actually wrong with your Mac or PC — it's not a cleaner. It finds the real cause and fixes it.

    InstallerClean finds and removes unneeded files from C:\Windows\Installer, the hidden folder on every Windows PC that quietly accumulates installer copies and patch files. Windows never cleans this folder up. Disk Cleanup doesn't touch it.

    Lightweight, open source, secure, no install needed. One script, no bloat, no ads, no telemetry. Does what CCleaner used to do before it became adware. Runs parallel (8-13 tasks at once), never touches your passwords or browser sessions, and you can read every line of code before running it.
