MacWashing vs Pearcleaner
Checked both apps on the same Mac
Both apps checked the same Mac with the same files. Five tests: a Mac with a classic web developer stack, an iPhone developer’s Mac, a video editor’s Mac, a photographer’s Mac and an everyday user’s Mac. Below is how much junk each one found.
In short
| App | Web developer | iPhone developer | Video editor | Photographer | Everyday user |
|---|---|---|---|---|---|
| 25.34 GB | 37.77 GB | 25.76 GB | 23.35 GB | 22.75 GB | |
| 3.21 GB | 32.34 GB | 3.53 GB | 369 MB | 1.64 GB |
How much junk each app found: the user’s large files and the space macOS frees by itself are not counted. Green is the best result in a column.

Is Pearcleaner safe?
In our tests Pearcleaner offered to remove 5 things that could break something — marked ⚠ in the charts above.
- The whole Visual Studio Code data folder (1.0 GB) is offered as one row with «Delete Folder» — in 1 of 5 testsBesides caches it holds the user's settings (User/settings.json, keybindings, snippets), local history, unsaved-file backups and extension state.
- Visual Studio Code's user settings, keybindings, snippets and local file history — the user's own data, not a cache — in 1 of 5 tests
- Visual Studio Code's installed extensions and their settings (the rules database marks it as data) — in 1 of 5 tests
- The whole Xcode UserData folder is offered — in 1 of 5 testsBesides the SwiftUI preview devices it is where Xcode keeps the user's key bindings, code snippets, themes and breakpoints (the rules database marks it as data).
- The whole Adobe folder (3.37 GB) is offered as an «orphaned file» although Adobe Premiere Rush is installed — in 1 of 5 testsBesides the media cache it holds the media cache database (Media Cache) and Adobe's settings.
MacWashing removes only what its rules database knows, and leaves alone what it can’t explain. Apps and large files go to the Trash by default, so they can be put back.
