    • really awesome open source alternative, and also allows you to script the cleaning process through the CLI, which helps when you have to do it a lot. elrey741Mar 2020 • 3 agrees and 1 disagrees Disagree   Agree
    • 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. JohnFastmanDec 2016 • 22 agrees and 8 disagrees Disagree   Agree
    • Simplicity and the fact that it's Open Source and the flexibility of the software, because it's the only one which adapt his functionnality to the environment ! Guest • Oct 2016 • 23 agrees and 9 disagrees Disagree   Agree
    • Coming from Linux, seems to clean a lot of things in Windows. Don't check all the function, read the hints for each one ! I never had trouble with this soft at the time. adresweb2bJun 2018 • 2 agrees and 0 disagrees Disagree   Agree
    • It supports all/most operating systems (including Linux - which doesn't get enough credit) and it is an open source software. Guest • Apr 2018 • 3 agrees and 1 disagrees Disagree   Agree
    • Great that it's open source, however it tends to be relatively slow at actually deleting some types of data. It does warn you, but it should be performing much quicker on an i7 6700k OC'd, with an M.2 drive. Guest • Oct 2017 • 0 agrees and 6 disagrees Disagree   Agree
    • As said its better in windows i used it,it doesnt have a pretty apparience but it does its job Guest • May 2017 • 7 agrees and 5 disagrees Disagree   Agree
    • While still not a perfect alternative, it has many of CCleaner's features and none of its malicious behavior. JohnDangerbrooksApr 2020 • 3 agrees and 1 disagrees Disagree   Agree
    • BB is Free (Libre) and Free (gratis). It can be used to free up space in your disks as well as to protect your privacy by deleting cookies, flash cookies, log files and similar. And because it's free (gratis) it does not include bloatware, malware, spyware commercials or anything of that sort. Guest • Jan 2018 • 15 agrees and 5 disagrees Disagree   Agree
    • BlechBit is not just a good alternative; it is the only alternative between the random assortment of items I see here. Guest • Jul 2019 • 5 agrees and 7 disagrees Disagree   Agree
    • much better than ccleaner after ccleaner got bought by avast. has multiple options and more ways to clear hdd/ssd space than ccleaner. Guest • Nov 2018 • 4 agrees and 0 disagrees Disagree   Agree
    • Not enough options and wipes extra settings in Chrome, like it closes all bookmark folders that are tedious to re-open as I need. It's just not similar enough, not that it's bad for most users. Guest • Jul 2019 • 3 agrees and 16 disagrees Disagree   Agree
    • It does not clean Opera history and probably same is with Chrome. i did not check chrome. Guest • Aug 2018 • 1 agrees and 6 disagrees Disagree   Agree
    • portable version does not require an install Guest • Jun 2017 • 4 agrees and 1 disagrees Disagree   Agree
    • Awesome piece of software, quite useful. Guest • Feb 2017 • 1 agrees and 0 disagrees Disagree   Agree
    • BleachBit only cleans the profile of the person logged in. It does not clean multiple users. Guest • Jan 2017 • 3 agrees and 9 disagrees Disagree   Agree
