Single Word for "removing unused stuff" [closed]

Looking for a single word for the term:

"removing unused stuff".

Edit:

To be used in the following context:

I am to use this word for a program that does some cleaning of useless stuff. But I want to avoid software lingo like erase/delete kind of things as they are already day to day usage for my audience.

I am looking for connotations that make it sound more funny or creative.

So rather than using XYZcleaner or XYZdeleter, something more fancy.

Purge.

As noted in the comments, "prune" works. But since it refers mainly to gardening, it conveys a sense of trimming back useful things that are overgrown.

I think this conveys clearing out things that aren't useful and getting down to basic essentials.

I would suggest one very universal word eliminate. Anyway, there could be many possibilities since stuff can stand for several meanings. For example, if the stuff is information, then erase/delete.
