Make sure all files of your hack are stored on a FAT storage device (flashdrive), otherwise its logged in the USN Journal. If your hacks were ever stored or touched your C: or other drives then you need to enter this in cmd (run as admin): fsutil usn deletejournal /n c: (please note you won't be able to play VAC secured servers for around an hour after running this)
When switching Steam accounts go to the top left menu on Steam client and click exit, after exiting run CCleaner and just make sure it deletes some Steam files (it will tell you what it deletes and how many).
If you want some other extra security tips feel free to add my skype: climbingtheskinladder
