When building a derivation, I am not proficient enough to get it right on the first try. For me it is a matter of trial and error.
During this, I gather a lot of nix store objects which I do not required nor want after I got my working derivation.
What is the best way to clean up the nix store?
For example, this is the nix store of a recent derivation I built:

The directory 1cj2wqiyyyjbizhy6sd4xv6l1larndvc-master-pdf-editor-5.8.20 contains the working derivation and i manually deleted all other directories with nix-store --delete.
I am not sure which of these other objects I can safely delete to clean up the nix store without breaking anything.
