About the ThemeSweep: Leftover Code

When you uninstall Shopify apps, they often leave code behind in your theme — orphaned snippets, unused CSS, dead scripts, and leftover Liquid that slow down your store. ThemeSweep scans your active theme to detect this dead code and shows you exactly which app left it. You get a clear report first, so nothing changes without your approval. Remove leftover code in one click with automatic theme backup and rollback protection, or use quarantine mode to comment it out instead. Every cleanup creates a full backup that you can restore instantly if needed. All backups are kept for 30 days, giving you complete peace of mind while cleaning up JavaScript, CSS, Liquid files, and orphan snippets from old apps.

Launched: September 7, 2026
