The "catch" to using CleanSlate is, of course, that you have to remember 
to load it _before_ doing any evaluations that define things you later 
want to erase. My own experience is that, on those occasions when it 
turns out I need it, I neglected to load it early enough.

So if this is a situation the O.P. expects to encounter frequently, it 
would be a good idea to load CleanSlate in an init.m.
