Remove Sample Data is a free Joomla 5 and 6 extension that detects and removes every item Joomla's Blog and Multilingual sample-data plugins install — articles, categories, tags, menus, modules, custom fields, workflows, the whole pile — with a preview, per-item opt-out, and a full activity log. One click, about 80 items gone, no leftover "same alias" collisions next time you reinstall sample data.
