So my suggestion would be for you will be keep removing these unwanted files from time to time.Currently , if you are looking for such kind of software, then Bleachbit. is what you will be looking forward too.
Though it not as popular as compare to CClearner on windows platform, but due to its open source development , this software many advantage over its competitor. It not only free your disk space but also Free cache, delete cookies, clear Internet history, shred temporary files, delete logs, and discard junk you didn't know was there. It support thousand of application including Firefox, Internet Explorer, Adobe Flash, Google Chrome, Opera ,Safari, and wipe the leftover files in a single go.
Software also support some advance feature like shredding files to prevent recovery, wiping free disk space to hide traces of files deleted by other applications, and vacuuming Firefox to make it faster.
One thing more its free, no advertisement (that will annoy you) and a huge support of open community to address your problem.
