Remove every modifier whose target has gone missing, from every selected Chisel object, in one click.

## The red rows

A Boolean, Emboss, Engrave or Carve modifier needs a target shape. Delete that shape, or unlink it from every collection, and the modifier can no longer do anything. Its row in the Chisel Modifiers panel turns red and reads *Difference: (no target)*, *Engrave: (no target)*, *Carve: (no target)*. The same happens when you add one of those modifiers from the panel menu and never pick a target.

**Clean Mods** removes all of them at once. Every other modifier (mirrors, arrays, deformers, booleans that still have their target) stays where it is.

## Where it lives

- **Object Properties → SDF**: the *Clean Mods* button, right under *Clean*
- **Right-click menu**: *Clean Mods*, after *Clean*
- **Pie menu** (`Q`): the unlink icon beside *Clean* in the North wedge
- **Chisel Modifiers panel**: in the options menu (the three-dot button), after *Delete All*

## How to use

1. Select the Chisel objects.
2. Click **Clean Mods**.

The report tells you how many modifiers were removed from how many objects. When nothing selected has a broken row the button is greyed out, and its tooltip explains why: *"Select a Chisel object with a red (no target) modifier first"*.

## Clean or Clean Mods?

| | What it acts on | What it removes |
|---|---|---|
| **[Clean](clean.md)** | The selected *operands*: cutters and stamps | The modifiers on their parents that use them, then unparents them and makes them solid |
| **Clean Mods** *(this page)* | The selected *hosts*: objects carrying modifiers | Only the modifiers whose target is gone |

Use **Clean** to keep a cutter as a shape of its own. Use **Clean Mods** to remove the rows deleted cutters left behind.
