How do I delete Blender 2.58 to re-download it again?

I love Blender and I have every intention of downloading it onto my computer again, but I was just wondering, how do I safely delete Blender 2.58 if I downloaded it from the Blender website?

Thanks.

Operating system ?
Did you use the installer or zip file ?

The installer

By all means, use the .zip download and just extract it to the directory of your choice. To get rid of it, just delete the directory (or the files within that you wish to have made new).
–EDIT–
If you used gasp the installer, then add or remove programs from the conrtrol panel should do the trick.

There will probably be an uninstall option in Add/Remove programs (or whatever it is currently called) just like any other installed program.
