How cleaning works.
You find stuff you haven't seen in years, that you'd forgotten (or never even knew) you had, and that you never use. So you throw it away.
Within a few days you realize you need the item desperately and they don't make them anymore.
I once donated a copy of the Dune Encyclopedia to the Mountain View Public Library (first edition, of course) because I couldn't afford to ship it across the continent to my new home. 15 years later I found one just like it at the Fort Lauderdale book fair for sale for $500.
