- Chuck7 thinks this post on BleachBit is helpfulIt works, easy to use, straight forward. Even for someone like me, a person who knows very little about technology.
Open source app Bleachbit is works wonders for removing all kinds of residual files and other traces of activity on your Windows or Linux computer. It is therefore a privacy- and security-enhancing tool. Security researcher Bruce Schneier, who handled some of the leaked Snowden files, has used Bleachbit (amongst other things) to keep his computer clean and secure against NSA spying.
Bleachbit is also allegedly the app Hillary Clinton (or her staff) used to erase those infamous emails. Hillariously (pun partially intended), during one of the 2016 US presidential debates, Donald Trump accused Hillary Clinton of "bleaching" her emails, calling it "a very expensive process".
Rest assured that Trump made that up: Bleachbit is open source, free, and costs nothing to use. Oh, and also you don't have to pay for it.
(Except perhaps that its use might attract misleading statements from Donald Trump.)
Bleachbit is able to go very deep and will delete a lot of things you wouldn't even know your computer keeps. I have never encountered any situation in which data has been deleted I didn't want it to. It does not break your registry or similar. It has also solved problems when not being able so install certain software.
A second feature besides just cleaning your system is that you are able to "shread with bleachbit" which will delete files and its digital footprint on your hard drive by changing its name and then deleting again. I recommend it to all my customers and friends.
Eating my CPU but no window is present. Kinda like a malware, except this pretends it helps you.
Much better than the spyware CCleaner. Kind of slow startup occasionally, though.
Its open source and free!!
Doesn't even open even tho the process is running. Tried old version too, have the same issue.
For me as well and I see people downvoting. They should work on making their program work, that'd be a better use.

Only shreds one file at a time via the right-click context menu. Other file shredders like Eraser and CyberShred do all the files you've selected. You can do multiple files at once with Bleachbit, but you need to open the program first and click-drag the files into it. Very jarring and clunky once you've had the convenience of "right-click > Shred" with other file shredders. Not sure how it is with cleaning compared to CCleaner, I only wanted it for file shredding.

EDIT: Forgot, I also used it to wipe free disk space, which seemed to work well.
