CleanSlate has an option, Verbose, which controls the printing of its
diagnostic message. Set it to False to turn it off:

CleanSlate[Verbose->False]

CleanSlate's documentation (which I seriously don't expect anyone to
read) desribes the things it resets and the things it doesn't. You
mention some things that it makes no attempt to restore. It would be
just too much effort (meaning memory use and computation time) to try
to completely reset the state of the kernel. As you note, if you
really want that, you can just quit and restart the kernel.
