True deletion of products is not supported. When you delete a product, its ID remains permanently in the system and cannot be reused. The product is effectively archived — see Archiving products for details on what archiving means and how to restore a product.
To delete (archive) a product:
Click the dotted menu icon (⋯) next to the relevant product.
Select Delete from the menu options.
In the confirmation modal, click Delete to complete the action.
