Something that will totally clean MEPIS? No such thing.

Applications that purport to automatically cleanse or optimize operating systems should be avoided IMO. There are applications that can help eliminate "unnecessary" and "duplicate" files, such as Bleachbit (one that you mentioned), Sweeper, and Komparator. But I would advise using these with caution. Unless you are in a severe crunch for disk space, having extra files spinning around on the HDD will have no detrimental effects on your system.

Install aptitude,
In Konsole as root
aptitude search ~c
aptitude purge $(aptitude search ~c -F "%p")
-------------------------------------------------
Delete the apps found, and that will get rid of all the junk.

This is an example of how it works, after doing an upgrade to sid and installing KDE 4.7.

You are used to Ubuntu, Mepis is different in the way you install apps, we do not use sudo we use su,
Open Konsole
type in su and press Enter
enter your root password, then press enter and you will be in root.
apt-get update
when it has updated.
apt-get install aptitude
then
aptitude update
aptitude search ~c
which will give you a list of files if there are any, then enter,
aptitude purge $(aptitude search ~c -F "%p")
to delete any files listed
