Documented steps
Find the active store location with pnpm store path (each drive/filesystem has its own store).
Check store integrity with pnpm store status — exit code 0 means no package content was modified since unpacking.
Run pnpm store prune to delete unreferenced packages (packages not used by any project on the system); pnpm prints the total size of removed files.
If a pruned package is needed again later, pnpm simply re-downloads it — the docs state prune 'is not harmful and has no side effects on your projects'.

Known gotchas
Run prune occasionally, not frequently: switching branches back to older dependency sets forces re-downloading everything you just pruned.
pnpm never garbage-collects old package versions on its own — disk usage grows until you prune.
With the global virtual store enabled, store prune also performs mark-and-sweep garbage collection on the store's links/ directory.
