	There is a package called "CleanSlate" which will utterly
restore Mathematica to its condition at start-up.  But if you don't
feel like hunting that down, Clear["Global`*"] should do the trick
rather easily.  Or define a function such as this at the start of each
session:

AllClear[]:= (
	confirm =
	StringTake[InputString["Confirm clear by typing 'y'"],1]=="y";
	If[confirm, (ClearAll["Global`*"];Remove["Global`*"]),Null]);
Protect[AllClear];

You can omit the prompt if you want, of course, like so:

AllClear[]:=(ClearAll["Global`*"]; Remove["Global`*"]);
Protect[AllClear];
