Attribute Cleaner

Attribute Cleaner is a Magento 2 extension that finds and removes unused product, category, customer and customer address attributes. Clear attributes that no longer serve your store but still clutter attribute sets, filters, import templates and product forms.

How Attribute Cleaner identifies unused attributes

Only user-defined attributes qualify for deletion. System attributes such as name, price, SKU, status and image roles never appear as deletion candidates. The extension keeps an attribute when:

• A record holds a value for it.
• An installed extension or custom theme creates, reads or displays it. Checks cover code, templates, XML, UI components and model classes, including Hyvä themes.
• Magento created it, unless you enable deletion of Magento-created attributes.
• A configurable product uses it as an option.
• A catalog or cart price rule, widget, CMS page or block, Page Builder template, or category or product content names it.
• A setting selects it, your Never Delete list includes it, or a custom table holds its values.

Each kept attribute shows its reason, so you can review why the extension excludes it from cleanup.

Review leftover values and missing model classes

The extension separately lists attributes with values on products or categories outside their attribute set. You can delete these attributes, and the backup retains their leftover values.

It also flags attributes whose model class no longer exists, which can point to a removed extension.

Delete attributes and restore backups

1. Open Stores › Attributes › Unused Attributes to review the results.
2. Select the attributes to delete. The extension checks each one again before deletion and saves a JSON backup in var/ before the first deletion.
3. Use the Backups list when you need to restore deleted attributes.

Restoration includes attribute IDs, labels, options and swatches, attribute set and group assignments, customer form settings and leftover values.

Take a database backup before large cleanups, as recommended for any bulk change.

Admin settings and command-line tools

Configure the Never Delete list and permission to delete Magento-created attributes in the extension settings under Stores › Configuration › Techimprovement.

• Run command-line scans with reasons, clean with a dry run, and restore backups.
• Control viewing, deleting and restoring through separate ACL resources.
• Refresh cached file checks with Check Files Again or a cache flush.

Requirements and included download

• Magento Open Source / Adobe Commerce 2.4.9.

The extension runs only in the Admin and command line and adds nothing to the storefront. It works independently of your storefront theme, including Luma, Luma-based and Hyvä themes.
