Cleaning up the computer involves more risks (of damaging the OS and sending it into the Dimension X) than when installing new software packages. It is because some of the packages have dependencies that are attached to some other places in the OS.

Why should I clean up my linux platform?
- To improve the performance
- To get rid of the zombies (if any)
- To free more space on the hard disk
- To keep your OS in good shape, etc.

The easy way?
Run Bleachbit and Bleachbit as Administrator.
If you don't have the Bleachbit package installed, from the system menu select ... Add/Remove Software, in the search box write: bleachbit 
and install the package.

Go to root/tmp, check what you have there (with dir), and delete the temporary files: rm -fR * (do not use this command in another directory).

Deactivate the services you don't use - don't touch the basic services: network manager, auditd, ip6 tables, iptables, messagebus, port reserve, rpcbind, rsyslog, sendmail - for you may send your OS beyond recovery.

Look for zombie processes:
$ ps -A s
and kill the zombies.

Uninstall all the programs you don't use and you don't intend to use in the near future with the Package Manager - any redundant word processors, viewers, messengers, virtual machines, etc.

When you uninstall spell checkers, thesauruses, menu localization be careful what you are uninstalling as dependencies.

How many browsers do you have and how many of them do you use?
Leave no more than two Internet Browsers on you computer.

What about the old kernels:
Check all the kernels that you have installed in the system:
$ rpm -qa | grep kernel
Check the currently connected kernels:
$ rpm -q kernel
Remove the old versions of the kernel that you don't use:
$ rpm -e kernel-version

Proceed in the same way with all the packages that you have multiple installation of: browsers, flash players, etc. Don't touch the Internet applets - some of them could not be recovered.

See how many .PDF readers do you have in the system - besides the Adobe Reader.
When you finish the clearance you will have a brand new operation system.

Well, it may not be Everest, but is one more gear to the top.
