[Newbies] Proper object removal

After much help already, I think I need some training in proper object

When my application creates an object and stores it in an OrderedCollection,
and than wants to delete it, I am trying to do so quite explicitly with
something like:

    self selected do: [:each |
        self abstractors remove: each.
        each := nil.

which removes the object from my application (it's collection), and yet when
I look for my object in the system with

DataAbstractor allInstances.

I still see the object I removed, even with an explicit Smalltalk
garbageCollect or garbageCollectMost.  Anything I create just seems to hang
around forever.

Any help understanding what I need to do to make sure my objects really go
away when I am done with them would be greatly appreciated!
